/**
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
