/**

 * 
 * The boolean grid filter allows you to create a filter selection that limits results
 * to values matching true or false.  The filter can be set programmatically or via 
 * user input with a configurable {@link Ext.menu.RadioItem radio item} in the filter section 
 * of the column header.
 * 
 * Boolean filters use unique radio group IDs, so you may utilize more than one.
