-/**
-   SelectCell is also a different kind of cell in that upon going into edit mode
-   the cell renders a list of options to pick from, as opposed to an input box.
-
-   SelectCell cannot be referenced by its string name when used in a column
-   definition because it requires an `optionValues` class attribute to be
-   defined. `optionValues` can either be a list of name-value pairs, to be
-   rendered as options, or a list of object hashes which consist of a key *name*
-   which is the option group name, and a key *values* which is a list of
-   name-value pairs to be rendered as options under that option group.
-
-   In addition, `optionValues` can also be a parameter-less function that
-   returns one of the above. If the options are static, it is recommended the
-   returned values to be memoized. `_.memoize()` is a good function to help with
-   that.
-
-   During display mode, the default formatter will normalize the raw model value
-   to an array of values whether the raw model value is a scalar or an
-   array. Each value is compared with the `optionValues` values using
-   Ecmascript's implicit type conversion rules. When exiting edit mode, no type
-   conversion is performed when saving into the model. This behavior is not
-   always desirable when the value type is anything other than string. To
-   control type conversion on the client-side, you should subclass SelectCell to
-   provide a custom formatter or provide the formatter to your column
-   definition.

-/**
-   Grid represents a data grid that has a header, body and an optional footer.
-
-   By default, a Grid treats each model in a collection as a row, and each
-   attribute in a model as a column. To render a grid you must provide a list of
-   column metadata and a collection to the Grid constructor. Just like any
-   Backbone.View class, the grid is rendered as a DOM node fragment when you
-   call render().
-
-       var grid = Backgrid.Grid({
-         columns: [{ name: "id", label: "ID", type: "string" },
-          // ...
-         ],
-         collections: books
-       });
-
-       $("#table-container").append(grid.render().el);
-
-   Optionally, if you want to customize the rendering of the grid's header and
-   footer, you may choose to extend Backgrid.Header and Backgrid.Footer, and
-   then supply that class or an instance of that class to the Grid constructor.
-   See the documentation for Header and Footer for further details.
-
-       var grid = Backgrid.Grid({
-         columns: [{ name: "id", label: "ID", type: "string" }],
-         collections: books,
-         header: Backgrid.Header.extend({
-              //...
-         }),
-         footer: Backgrid.Paginator
-       });
-
-   Finally, if you want to override how the rows are rendered in the table body,
-   you can supply a Body subclass as the `body` attribute that uses a different
-   Row class.
-
-   @class Backgrid.Grid
-   @extends Backbone.View

-
-   - Backgrid.Column
