| Extends: | Object | 
A Column subclass which renders a checkbox in each column cell which toggles the truthiness of the associated data field on click.
Note. As of ExtJS 3.3 this no longer has to be configured as a plugin of the GridPanel.
Example usage:
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,
    ...
});
