+/**
+ * A JSONArray is an ordered sequence of values. Its external text form is a
+ * string wrapped in square brackets with commas separating the values. The
+ * internal form is an object having <code>get</code> and <code>opt</code>
+ * methods for accessing the values by index, and <code>put</code> methods for
+ * adding or replacing values. The values can be any of these types:
+ * <code>Boolean</code>, <code>JSONArray</code>, <code>JSONObject</code>,
+ * <code>Number</code>, <code>String</code>, or the
+ * <code>JSONObject.NULL object</code>.
+ * <p>
+ * The constructor can convert a JSON text into a Java object. The
+ * <code>toString</code> method converts to JSON text.
+ * <p>
+ * A <code>get</code> method returns a value if one can be found, and throws an
+ * exception if one cannot be found. An <code>opt</code> method returns a
+ * default value instead of throwing an exception, and so is useful for
+ * obtaining optional values.
+ * <p>
+ * The generic <code>get()</code> and <code>opt()</code> methods return an
+ * object which you can cast or query for type. There are also typed
+ * <code>get</code> and <code>opt</code> methods that do type checking and type
+ * coersion for you.
+ * <p>
+ * The texts produced by the <code>toString</code> methods strictly conform to
+ * JSON syntax rules. The constructors are more forgiving in the texts they will
+ * accept:
+ * <ul>
+ * <li>An extra <code>,</code>&nbsp;<small>(comma)</small> may appear just
+ *     before the closing bracket.</li>
+ * <li>The <code>null</code> value will be inserted when there
+ *     is <code>,</code>&nbsp;<small>(comma)</small> elision.</li>
+ * <li>Strings may be quoted with <code>'</code>&nbsp;<small>(single
+ *     quote)</small>.</li>
+ * <li>Strings do not need to be quoted at all if they do not begin with a quote
+ *     or single quote, and if they do not contain leading or trailing spaces,
+ *     and if they do not contain any of these characters:
+ *     <code>{ } [ ] / \ : , = ; #</code> and if they do not look like numbers
+ *     and if they are not the reserved words <code>true</code>,
+ *     <code>false</code>, or <code>null</code>.</li>
+ * <li>Values can be separated by <code>;</code> <small>(semicolon)</small> as
+ *     well as by <code>,</code> <small>(comma)</small>.</li>
+ * <li>Numbers may have the <code>0-</code> <small>(octal)</small> or
+ *     <code>0x-</code> <small>(hex)</small> prefix.</li>
+ * <li>Comments written in the slashshlash, slashstar, and hash conventions
+ *     will be ignored.</li>
+ * </ul>

+/**
+ * A JSONObject is an unordered collection of name/value pairs. Its
+ * external form is a string wrapped in curly braces with colons between the
+ * names and values, and commas between the values and names. The internal form
+ * is an object having <code>get</code> and <code>opt</code> methods for
+ * accessing the values by name, and <code>put</code> methods for adding or
+ * replacing values by name. The values can be any of these types:
+ * <code>Boolean</code>, <code>JSONArray</code>, <code>JSONObject</code>,
+ * <code>Number</code>, <code>String</code>, or the <code>JSONObject.NULL</code>
+ * object. A JSONObject constructor can be used to convert an external form
+ * JSON text into an internal form whose values can be retrieved with the
+ * <code>get</code> and <code>opt</code> methods, or to convert values into a
+ * JSON text using the <code>put</code> and <code>toString</code> methods.
+ * A <code>get</code> method returns a value if one can be found, and throws an
+ * exception if one cannot be found. An <code>opt</code> method returns a
+ * default value instead of throwing an exception, and so is useful for
+ * obtaining optional values.
+ * <p>
+ * The generic <code>get()</code> and <code>opt()</code> methods return an
+ * object, which you can cast or query for type. There are also typed
+ * <code>get</code> and <code>opt</code> methods that do type checking and type
+ * coersion for you.
+ * <p>
+ * The <code>put</code> methods adds values to an object. For example, <pre>
+ *     myString = new JSONObject().put("JSON", "Hello, World!").toString();</pre>
+ * produces the string <code>{"JSON": "Hello, World"}</code>.
+ * <p>
+ * The texts produced by the <code>toString</code> methods strictly conform to
+ * the JSON sysntax rules.
+ * The constructors are more forgiving in the texts they will accept:
+ * <ul>
+ * <li>An extra <code>,</code>&nbsp;<small>(comma)</small> may appear just
+ *     before the closing brace.</li>
+ * <li>Strings may be quoted with <code>'</code>&nbsp;<small>(single
+ *     quote)</small>.</li>
+ * <li>Strings do not need to be quoted at all if they do not begin with a quote
+ *     or single quote, and if they do not contain leading or trailing spaces,
+ *     and if they do not contain any of these characters:
+ *     <code>{ } [ ] / \ : , = ; #</code> and if they do not look like numbers
+ *     and if they are not the reserved words <code>true</code>,
+ *     <code>false</code>, or <code>null</code>.</li>
+ * <li>Keys can be followed by <code>=</code> or <code>=></code> as well as
+ *     by <code>:</code>.</li>
+ * <li>Values can be followed by <code>;</code> <small>(semicolon)</small> as
+ *     well as by <code>,</code> <small>(comma)</small>.</li>
+ * <li>Numbers may have the <code>0-</code> <small>(octal)</small> or
+ *     <code>0x-</code> <small>(hex)</small> prefix.</li>
+ * <li>Comments written in the slashshlash, slashstar, and hash conventions
+ *     will be ignored.</li>
