-    <p>
-      <a href="http://github.com/documentcloud/underscore/">Underscore</a> is a
-      utility-belt library for JavaScript that provides a lot of the
-      functional programming support that you would expect in
-      <a href="http://prototypejs.org/doc/latest/">Prototype.js</a>
-      (or <a href="http://www.ruby-doc.org/core/classes/Enumerable.html">Ruby</a>),
-      but without extending any of the built-in JavaScript objects. It's the
-      tie to go along with <a href="http://docs.jquery.com">jQuery</a>'s tux,
-      and <a href="http://backbonejs.org">Backbone.js</a>'s suspenders.
-    </p>
-
-    <p>
-      Underscore provides 80-odd functions that support both the usual
-      functional suspects: <b>map</b>, <b>select</b>, <b>invoke</b> &mdash;
-      as well as more specialized helpers: function binding, javascript
-      templating, deep equality testing, and so on. It delegates to built-in
-      functions, if present, so modern browsers will use the
-      native implementations of <b>forEach</b>, <b>map</b>, <b>reduce</b>,
-      <b>filter</b>, <b>every</b>, <b>some</b> and <b>indexOf</b>.
-    </p>

-      <p id="bindAll">
-        <b class="header">bindAll</b><code>_.bindAll(object, [*methodNames])</code>
-        <br />
-        Binds a number of methods on the <b>object</b>, specified by
-        <b>methodNames</b>, to be run in the context of that object whenever they
-        are invoked. Very handy for binding functions that are going to be used
-        as event handlers, which would otherwise be invoked with a fairly useless
-        <i>this</i>. If no <b>methodNames</b> are provided, all of the object's
-        function properties will be bound to it.
-      </p>

-
-      <p id="memoize">
-        <b class="header">memoize</b><code>_.memoize(function, [hashFunction])</code>
-        <br />
-        Memoizes a given <b>function</b> by caching the computed result. Useful
-        for speeding up slow-running computations. If passed an optional
-        <b>hashFunction</b>, it will be used to compute the hash key for storing
-        the result, based on the arguments to the original function. The default
-        <b>hashFunction</b> just uses the first argument to the memoized function
-        as the key.
-      </p>
-      <pre>
-var fibonacci = _.memoize(function(n) {
-  return n &lt; 2 ? n : fibonacci(n - 1) + fibonacci(n - 2);

-      <p id="delay">
-        <b class="header">delay</b><code>_.delay(function, wait, [*arguments])</code>
-        <br />
-        Much like <b>setTimeout</b>, invokes <b>function</b> after <b>wait</b>
-        milliseconds. If you pass the optional <b>arguments</b>, they will be
-        forwarded on to the <b>function</b> when it is invoked.
-      </p>
-      <pre>
-var log = _.bind(console.log, console);
-_.delay(log, 1000, 'logged later');
-=&gt; 'logged later' // Appears after one second.
-</pre>
-
-      <p id="defer">
-        <b class="header">defer</b><code>_.defer(function, [*arguments])</code>
-        <br />
-        Defers invoking the <b>function</b> until the current call stack has cleared,
-        similar to using <b>setTimeout</b> with a delay of 0. Useful for performing
-        expensive computations or HTML rendering in chunks without blocking the UI thread
-        from updating. If you pass the optional <b>arguments</b>, they will be
-        forwarded on to the <b>function</b> when it is invoked.
-      </p>
-      <pre>

-</pre>
-
-      <p id="throttle">
-        <b class="header">throttle</b><code>_.throttle(function, wait)</code>
-        <br />
-        Creates and returns a new, throttled version of the passed function,
-        that, when invoked repeatedly, will only actually call the original function
-        at most once per every <b>wait</b>
-        milliseconds. Useful for rate-limiting events that occur faster than you
-        can keep up with.
-      </p>
-      <pre>
-var throttled = _.throttle(updatePosition, 100);

-
-      <p id="debounce">
-        <b class="header">debounce</b><code>_.debounce(function, wait, [immediate])</code>
-        <br />
-        Creates and returns a new debounced version of the passed function that
-        will postpone its execution until after
-        <b>wait</b> milliseconds have elapsed since the last time it
-        was invoked. Useful for implementing behavior that should only happen
-        <i>after</i> the input has stopped arriving. For example: rendering a
-        preview of a Markdown comment, recalculating a layout after the window
-        has stopped being resized, and so on.
-      </p>
-
-      <p>
-        Pass <tt>true</tt> for the <b>immediate</b> parameter to cause
-        <b>debounce</b> to trigger the function on the leading instead of the
-        trailing edge of the <b>wait</b> interval. Useful in circumstances like
-        preventing accidental double-clicks on a "submit" button from firing a
-        second time.

-        <b class="header">once</b><code>_.once(function)</code>
-        <br />
-        Creates a version of the function that can only be called one time.
-        Repeated calls to the modified function will have no effect, returning
-        the value from the original call. Useful for initialization functions,
-        instead of having to set a boolean flag and then check it later.
-      </p>
-      <pre>
-var initialize = _.once(createApplication);
-initialize();
-initialize();
-// Application is only created once.
-</pre>
-
-      <p id="after">
-        <b class="header">after</b><code>_.after(count, function)</code>
-        <br />
-        Creates a version of the function that will only be run after first
-        being called <b>count</b> times. Useful for grouping asynchronous responses,
-        where you want to be sure that all the async calls have finished, before
-        proceeding.
-      </p>
-      <pre>
-var renderNotes = _.after(notes.length, render);
-_.each(notes, function(note) {

-</pre>
-
-      <p id="wrap">
-        <b class="header">wrap</b><code>_.wrap(function, wrapper)</code>
-        <br />
-        Wraps the first <b>function</b> inside of the <b>wrapper</b> function,
-        passing it as the first argument. This allows the <b>wrapper</b> to
-        execute code before and after the <b>function</b> runs, adjust the arguments,
-        and execute it conditionally.
-      </p>
-      <pre>
-var hello = function(name) { return "hello: " + name; };
-hello = _.wrap(hello, function(func) {

-
-      <p id="compose">
-        <b class="header">compose</b><code>_.compose(*functions)</code>
-        <br />
-        Returns the composition of a list of <b>functions</b>, where each function
-        consumes the return value of the function that follows. In math terms,
-        composing the functions <i>f()</i>, <i>g()</i>, and <i>h()</i> produces

-        <b class="header">template</b><code>_.template(templateString, [data], [settings])</code>
-        <br />
-        Compiles JavaScript templates into functions that can be evaluated
-        for rendering. Useful for rendering complicated bits of HTML from JSON
-        data sources. Template functions can both interpolate variables, using
-        <tt>&lt;%= &hellip; %&gt;</tt>, as well as execute arbitrary JavaScript code, with
-        <tt>&lt;% &hellip; %&gt;</tt>. If you wish to interpolate a value, and have
-        it be HTML-escaped, use <tt>&lt;%- &hellip; %&gt;</tt> When you evaluate a template function, pass in a
-        <b>data</b> object that has properties corresponding to the template's free
-        variables. If you're writing a one-off, you can pass the <b>data</b>
-        object as the second parameter to <b>template</b> in order to render
-        immediately instead of returning a template function.  The <b>settings</b> argument
-        should be a hash containing any <tt>_.templateSettings</tt> that should be overridden.
-      </p>
-
-      <pre>
-var compiled = _.template("hello: &lt;%= name %&gt;");
-compiled({name : 'moe'});
-=&gt; "hello: moe"
-
-var list = "&lt;% _.each(people, function(name) { %&gt; &lt;li&gt;&lt;%= name %&gt;&lt;/li&gt; &lt;% }); %&gt;";
-_.template(list, {people : ['moe', 'curly', 'larry']});
-=&gt; "&lt;li&gt;moe&lt;/li&gt;&lt;li&gt;curly&lt;/li&gt;&lt;li&gt;larry&lt;/li&gt;"
-
-var template = _.template("&lt;b&gt;&lt;%- value %&gt;&lt;/b&gt;");
-template({value : '&lt;script&gt;'});
-=&gt; "&lt;b&gt;&amp;lt;script&amp;gt;&lt;/b&gt;"</pre>
-
-      <p>
-        You can also use <tt>print</tt> from within JavaScript code.  This is
-        sometimes more convenient than using <tt>&lt;%= ... %&gt;</tt>.
-      </p>
-
-      <pre>
-var compiled = _.template("&lt;% print('Hello ' + epithet); %&gt;");
-compiled({epithet: "stooge"});
-=&gt; "Hello stooge."</pre>
-
-      <p>
-        If ERB-style delimiters aren't your cup of tea, you can change Underscore's
-        template settings to use different symbols to set off interpolated code.
-        Define an <b>interpolate</b> regex to match expressions that should be
-        interpolated verbatim, an <b>escape</b> regex to match expressions that should
-        be inserted after being HTML escaped, and an <b>evaluate</b> regex to match
-        expressions that should be evaluated without insertion into the resulting
-        string. You may define or omit any combination of the three.
-        For example, to perform
-        <a href="http://github.com/janl/mustache.js#readme">Mustache.js</a>
-        style templating:
-      </p>
-
-      <pre>
-_.templateSettings = {
-  interpolate : /\{\{(.+?)\}\}/g
-};
-
-var template = _.template("Hello {{ name }}!");
-template({name : "Mustache"});
-=&gt; "Hello Mustache!"</pre>
-
-      <p>
-        By default, <b>template</b> places the values from your data in the local scope
-        via the <tt>with</tt> statement.  However, you can specify a single variable name
-        with the <b>variable</b> setting. This can significantly improve the speed
-        at which a template is able to render.
-      </p>
-
-      <pre>
-_.template("Using 'with': <%= data.answer %>", {answer: 'no'}, {variable: 'data'});
-=&gt; "Using 'with': no"</pre>
-
-      <p>
-        Precompiling your templates can be a big help when debugging errors you can't
-        reproduce.  This is because precompiled templates can provide line numbers and
-        a stack trace, something that is not possible when compiling templates on the client.
-        The <b>source</b> property is available on the compiled template
-        function for easy precompilation.
-      </p>
-
-      <pre>&lt;script&gt;
-  JST.project = <%= _.template(jstText).source %>;

-        You can use Underscore in either an object-oriented or a functional style,

-        <ul>
-          <li>
-            Many improvements to <tt>_.template</tt>, which now provides the
-            <tt>source</tt> of the template function as a property, for potentially
-            even more efficient pre-compilation on the server-side. You may now
-            also set the <tt>variable</tt> option when creating a template,
-            which will cause your passed-in data to be made available under the
-            variable you named, instead of using a <tt>with</tt> statement &mdash;
-            significantly improving the speed of rendering the template.
-          </li>
-          <li>
-            Added the <tt>pick</tt> function, which allows you to filter an
-            object literal with a whitelist of allowed property names.
-          </li>
-          <li>
-            Added the <tt>result</tt> function, for convenience when working
-            with APIs that allow either functions or raw properties.
-          </li>
-          <li>
-            Added the <tt>isFinite</tt> function, because sometimes knowing that
-            a value is a number just ain't quite enough.
-          </li>
-          <li>
-            The <tt>sortBy</tt> function may now also be passed the string name
-            of a property to use as the sort order on each object.
-          </li>
-          <li>
-            Fixed <tt>uniq</tt> to work with sparse arrays.
-          </li>
-          <li>
-            The <tt>difference</tt> function now performs a shallow flatten
-            instead of a deep one when computing array differences.
-          </li>
-          <li>
-            The <tt>debounce</tt> function now takes an <tt>immediate</tt>
-            parameter, which will cause the callback to fire on the leading
-            instead of the trailing edge.
-          </li>

-        <ul>
-          <li>
-            Added an <tt>_.has</tt> function, as a safer way to use <tt>hasOwnProperty</tt>.
-          </li>
-          <li>
-            Added <tt>_.collect</tt> as an alias for <tt>_.map</tt>. Smalltalkers, rejoice.
-          </li>
-          <li>
-            Reverted an old change so that <tt>_.extend</tt> will correctly copy
-            over keys with undefined values again.
-          </li>
-          <li>
-            Bugfix to stop escaping slashes within interpolations in <tt>_.template</tt>.
-          </li>
-        </ul>

-        <b class="header">1.3.0</b> &mdash; <small><i>Jan. 11, 2012</i></small><br />
-        <ul>
-          <li>
-            Removed AMD (RequireJS) support from Underscore. If you'd like to use
-            Underscore with RequireJS, you can load it as a normal script, wrap
-            or patch your copy, or download a forked version.

-        <ul>
-          <li>
-            You now can (and probably should, as it's simpler)
-            write <tt>_.chain(list)</tt>
-            instead of <tt>_(list).chain()</tt>.
-          </li>
-          <li>
-            Fix for escaped characters in Underscore templates, and for supporting
-            customizations of <tt>_.templateSettings</tt> that only define one or
-            two of the required regexes.
-          </li>
-          <li>
-            Fix for passing an array as the first argument to an <tt>_.wrap</tt>'d function.
-          </li>
-          <li>
-            Improved compatibility with ClojureScript, which adds a <tt>call</tt>
-            function to <tt>String.prototype</tt>.
-          </li>
-        </ul>

-        <b class="header">1.2.3</b> &mdash; <small><i>Dec. 7, 2011</i></small><br />
-        <ul>
-          <li>
-            Dynamic scope is now preserved for compiled <tt>_.template</tt> functions,
-            so you can use the value of <tt>this</tt> if you like.
-          </li>
-          <li>
-            Sparse array support of <tt>_.indexOf</tt>, <tt>_.lastIndexOf</tt>.
-          </li>
-          <li>
-            Both <tt>_.reduce</tt> and <tt>_.reduceRight</tt> can now be passed an
-            explicitly <tt>undefined</tt> value. (There's no reason why you'd
-            want to do this.)
-          </li>

-        <b class="header">1.2.2</b> &mdash; <small><i>Nov. 14, 2011</i></small><br />
-        <ul>
-          <li>
-            Continued tweaks to <tt>_.isEqual</tt> semantics. Now JS primitives are
-            considered equivalent to their wrapped versions, and arrays are compared
-            by their numeric properties only <small>(#351)</small>.
-          </li>
-          <li>
-            <tt>_.escape</tt> no longer tries to be smart about not double-escaping
-            already-escaped HTML entities. Now it just escapes regardless <small>(#350)</small>.
-          </li>
-          <li>
-            In <tt>_.template</tt>, you may now leave semicolons out of evaluated
-            statements if you wish: <tt>&lt;% }) %&gt;</tt> <small>(#369)</small>.
-          </li>
-          <li>
-            <tt>_.after(callback, 0)</tt> will now trigger the callback immediately,
-            making "after" easier to use with asynchronous APIs <small>(#366)</small>.
-          </li>
-        </ul>

-        <ul>
-          <li>
-            Several important bug fixes for <tt>_.isEqual</tt>, which should now
-            do better on mutated Arrays, and on non-Array objects with
-            <tt>length</tt> properties. <small>(#329)</small>
-          </li>
-          <li>
-            <b>jrburke</b> contributed Underscore exporting for AMD module loaders,
-            and <b>tonylukasavage</b> for Appcelerator Titanium.
-            <small>(#335, #338)</small>
-          </li>
-          <li>
-            You can now <tt>_.groupBy(list, 'property')</tt> as a shortcut for
-            grouping values by a particular common property.
-          </li>
-          <li>
-            <tt>_.throttle</tt>'d functions now fire immediately upon invocation,
-            and are rate-limited thereafter <small>(#170, #266)</small>.
-          </li>
-          <li>
-            Most of the <tt>_.is[Type]</tt> checks no longer ducktype.
-          </li>
-          <li>
-            The <tt>_.bind</tt> function now also works on constructors, a-la
-            ES5 ... but you would never want to use <tt>_.bind</tt> on a
-            constructor function.
-          </li>
-          <li>
-            <tt>_.clone</tt> no longer wraps non-object types in Objects.
-          </li>
-          <li>
-            <tt>_.find</tt> and <tt>_.filter</tt> are now the preferred names for
-            <tt>_.detect</tt> and <tt>_.select</tt>.

-        <ul>
-          <li>
-            The <tt>_.isEqual</tt> function now
-            supports true deep equality comparisons, with checks for cyclic structures,
-            thanks to Kit Cambridge.
-          </li>
-          <li>
-            Underscore templates now support HTML escaping interpolations, using
-            <tt>&lt;%- ... %&gt;</tt> syntax.
-          </li>
-          <li>
-            Ryan Tenney contributed <tt>_.shuffle</tt>, which uses a modified
-            Fisher-Yates to give you a shuffled copy of an array.
-          </li>
-          <li>
-            <tt>_.uniq</tt> can now be passed an optional iterator, to determine by
-            what criteria an object should be considered unique.
-          </li>
-          <li>
-            <tt>_.last</tt> now takes an optional argument which will return the last
-            N elements of the list.
-          </li>
-          <li>
-            A new <tt>_.initial</tt> function was added, as a mirror of <tt>_.rest</tt>,
-            which returns all the initial values of a list (except the last N).
-          </li>
-        </ul>

-
-      <p>
-        <b class="header">1.1.7</b> &mdash; <small><i>July 13, 2011</i></small><br />
-        Added <tt>_.groupBy</tt>, which aggregates a collection into groups of like items.
-        Added <tt>_.union</tt> and <tt>_.difference</tt>, to complement the
-        (re-named) <tt>_.intersection</tt>.
-        Various improvements for support of sparse arrays.
-        <tt>_.toArray</tt> now returns a clone, if directly passed an array.
-        <tt>_.functions</tt> now also returns the names of functions that are present
-        in the prototype chain.
-      </p>
-
-      <p>
-        <b class="header">1.1.6</b> &mdash; <small><i>April 18, 2011</i></small><br />
-        Added <tt>_.after</tt>, which will return a function that only runs after
-        first being called a specified number of times.
-        <tt>_.invoke</tt> can now take a direct function reference.
-        <tt>_.every</tt> now requires an iterator function to be passed, which
-        mirrors the ECMA5 API.
-        <tt>_.extend</tt> no longer copies keys when the value is undefined.
-        <tt>_.bind</tt> now errors when trying to bind an undefined value.
-      </p>
-
-      <p>
-        <b class="header">1.1.5</b> &mdash; <small><i>Mar 20, 2011</i></small><br />
-        Added an <tt>_.defaults</tt> function, for use merging together JS objects
-        representing default options.
-        Added an <tt>_.once</tt> function, for manufacturing functions that should
-        only ever execute a single time.
-        <tt>_.bind</tt> now delegates to the native ECMAScript 5 version,
-        where available.
-        <tt>_.keys</tt> now throws an error when used on non-Object values, as in
-        ECMAScript 5.
-        Fixed a bug with <tt>_.keys</tt> when used over sparse arrays.
-      </p>
-
-      <p>
-        <b class="header">1.1.4</b> &mdash; <small><i>Jan 9, 2011</i></small><br />
-        Improved compliance with ES5's Array methods when passing <tt>null</tt>
-        as a value. <tt>_.wrap</tt> now correctly sets <tt>this</tt> for the
-        wrapped function. <tt>_.indexOf</tt> now takes an optional flag for
-        finding the insertion index in an array that is guaranteed to already
-        be sorted. Avoiding the use of <tt>.callee</tt>, to allow <tt>_.isArray</tt>
-        to work properly in ES5's strict mode.
-      </p>
-
-      <p>
-        <b class="header">1.1.3</b> &mdash; <small><i>Dec 1, 2010</i></small><br />
-        In CommonJS, Underscore may now be required with just: <br />
-        <tt>var _ = require("underscore")</tt>.
-        Added <tt>_.throttle</tt> and <tt>_.debounce</tt> functions.
-        Removed <tt>_.breakLoop</tt>, in favor of an ECMA5-style un-<i>break</i>-able
-        each implementation &mdash; this removes the try/catch, and you'll now have
-        better stack traces for exceptions that are thrown within an Underscore iterator.
-        Improved the <b>isType</b> family of functions for better interoperability
-        with Internet Explorer host objects.
-        <tt>_.template</tt> now correctly escapes backslashes in templates.
-        Improved <tt>_.reduce</tt> compatibility with the ECMA5 version:
-        if you don't pass an initial value, the first item in the collection is used.
-        <tt>_.each</tt> no longer returns the iterated collection, for improved
-        consistency with ES5's <tt>forEach</tt>.
-      </p>
-
-      <p>
-        <b class="header">1.1.2</b><br />
-        Fixed <tt>_.contains</tt>, which was mistakenly pointing at
-        <tt>_.intersect</tt> instead of <tt>_.include</tt>, like it should
-        have been. Added <tt>_.unique</tt> as an alias for <tt>_.uniq</tt>.
-      </p>
-
-      <p>
-        <b class="header">1.1.1</b><br />
-        Improved the speed of <tt>_.template</tt>, and its handling of multiline
-        interpolations. Ryan Tenney contributed optimizations to many Underscore
-        functions. An annotated version of the source code is now available.
-      </p>
-
-      <p>
-        <b class="header">1.1.0</b><br />
-        The method signature of <tt>_.reduce</tt> has been changed to match
-        the ECMAScript 5 signature, instead of the Ruby/Prototype.js version.
-        This is a backwards-incompatible change. <tt>_.template</tt> may now be
-        called with no arguments, and preserves whitespace. <tt>_.contains</tt>
-        is a new alias for <tt>_.include</tt>.
-      </p>
-
-      <p>
-        <b class="header">1.0.4</b><br />
-        <a href="http://themoell.com/">Andri Möll</a> contributed the <tt>_.memoize</tt>
-        function, which can be used to speed up expensive repeated computations
-        by caching the results.
-      </p>
-
-      <p>
-        <b class="header">1.0.3</b><br />
-        Patch that makes <tt>_.isEqual</tt> return <tt>false</tt> if any property
-        of the compared object has a <tt>NaN</tt> value. Technically the correct
-        thing to do, but of questionable semantics. Watch out for NaN comparisons.
-      </p>
-
-      <p>
-        <b class="header">1.0.2</b><br />
-        Fixes <tt>_.isArguments</tt> in recent versions of Opera, which have
-        arguments objects as real Arrays.
-      </p>
-
-      <p>
-        <b class="header">1.0.1</b><br />
-        Bugfix for <tt>_.isEqual</tt>, when comparing two objects with the same

-
-      <p>
-        <b class="header">1.0.0</b><br />
-        Things have been stable for many months now, so Underscore is now
-        considered to be out of beta, at <b>1.0</b>. Improvements since <b>0.6</b>
-        include <tt>_.isBoolean</tt>, and the ability to have <tt>_.extend</tt>

-        <b class="header">0.6.0</b><br />
-        Major release. Incorporates a number of

-        safer duck-typing on collection functions, and cleaner internals. A new
-        <tt>_.mixin</tt> method that allows you to extend Underscore with utility
-        functions of your own. Added <tt>_.times</tt>, which works the same as in
-        Ruby or Prototype.js. Native support for ECMAScript 5's <tt>Array.isArray</tt>,
-        and <tt>Object.keys</tt>.
-      </p>

-      <p>
-        <b class="header">0.5.8</b><br />
-        Fixed Underscore's collection functions to work on

-        <tt>isNumber</tt>, <tt>isRegExp</tt>, and <tt>isString</tt>, thanks to
-        a suggestion from
-        <a href="http://www.broofa.com/">Robert Kieffer</a>.
-        Instead of doing <tt>Object#toString</tt>
-        comparisons, they now check for expected properties, which is less safe,
-        but more than an order of magnitude faster. Most other Underscore
-        functions saw minor speed improvements as a result.
-        <a href="http://dolzhenko.org/">Evgeniy Dolzhenko</a>
-        contributed <tt>_.tap</tt>,
-        <a href="http://ruby-doc.org/core-1.9/classes/Object.html#M000191">similar to Ruby 1.9's</a>,
-        which is handy for injecting side effects (like logging) into chained calls.

-        Added an <tt>_.isArguments</tt> function. Lots of little safety checks

-        <b>[API Changes]</b> <tt>_.bindAll</tt> now takes the context object as
-        its first parameter. If no method names are passed, all of the context
-        object's methods are bound to it, enabling chaining and easier binding.
-        <tt>_.functions</tt> now takes a single argument and returns the names
-        of its Function properties. Calling <tt>_.functions(_)</tt> will get you
-        the previous behavior.
-        Added <tt>_.isRegExp</tt> so that <tt>isEqual</tt> can now test for RegExp equality.
-        All of the "is" functions have been shrunk down into a single definition.

-        <b class="header">0.4.7</b><br />
-        Added <tt>isDate</tt>, <tt>isNaN</tt>, and <tt>isNull</tt>, for completeness.
-        Optimizations for <tt>isEqual</tt> when checking equality between Arrays
-        or Dates. <tt>_.keys</tt> is now <small><i><b>25%&ndash;2X</b></i></small> faster (depending on your
-        browser) which speeds up the functions that rely on it, such as <tt>_.each</tt>.

-        <b class="header">0.4.6</b><br />
-        Added the <tt>range</tt> function, a port of the
-        <a href="http://docs.python.org/library/functions.html#range">Python
-        function of the same name</a>, for generating flexibly-numbered lists
-        of integers. Original patch contributed by

-        <b class="header">0.4.5</b><br />
-        Added <tt>rest</tt> for Arrays and arguments objects, and aliased
-        <tt>first</tt> as <tt>head</tt>, and <tt>rest</tt> as <tt>tail</tt>,
-        thanks to <a href="http://github.com/lukesutton/">Luke Sutton</a>'s patches.
-        Added tests ensuring that all Underscore Array functions also work on
-        <i>arguments</i> objects.

-        <b class="header">0.4.4</b><br />
-        Added <tt>isString</tt>, and <tt>isNumber</tt>, for consistency. Fixed
-        <tt>_.isEqual(NaN, NaN)</tt> to return <i>true</i> (which is debatable).

-        <b class="header">0.4.3</b><br />
-        Started using the native <tt>StopIteration</tt> object in browsers that support it.
