/**

 * GridFilter is a plugin for grids that allow for a slightly more robust
 * representation of filtering than what is provided by the default store.
 * </p>
 * <p>
 * Filtering is adjusted by the user using the grid's column header menu (this
 * menu can be disabled through configuration). Through this menu users can
 * configure, enable, and disable filters for each column.
