/**
 * @class Ext.ux.grid.CheckColumn
 * @extends Ext.grid.Column
 * <p>A Column subclass which renders a checkbox in each column cell which toggles the truthiness of the associated data field on click.</p>
 * <p><b>Note. As of ExtJS 3.3 this no longer has to be configured as a plugin of the GridPanel.</b></p>
 * <p>Example usage:</p>
 * <pre><code>
var cm = new Ext.grid.ColumnModel([{
       header: 'Foo',
       ...
    },{
       xtype: 'checkcolumn',
       header: 'Indoor?',
       dataIndex: 'indoor',
       width: 55
    }
]);

// create the grid
var grid = new Ext.grid.EditorGridPanel({
    ...
    colModel: cm,
    ...
});
 * </code></pre>
 * In addition to toggling a Boolean value within the record data, this
 * class toggles a css class between <tt>'x-grid3-check-col'</tt> and
 * <tt>'x-grid3-check-col-on'</tt> to alter the background image used for
 * a column.
