+/**
+ * @class Ext.ux.grid.CheckColumn
+ * @extends Ext.grid.Column
+ * 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,
+ ...
+});
+ *
+ * In addition to toggling a Boolean value within the record data, this
+ * class toggles a css class between 'x-grid3-check-col' and
+ * 'x-grid3-check-col-on' to alter the background image used for
+ * a column.
