 /**
 * @class Ext.ux.GridPrinter
 * @author Ed Spencer ([email protected])
 * Helper class to easily print the contents of a grid. Will open a new window with a table where the first row
 * contains the headings from your column model, and with a row for each item in your grid's store. When formatted
 * with appropriate CSS it should look very similar to a default grid. If renderers are specified in your column
 * model, they will be used in creating the table. Override headerTpl and bodyTpl to change how the markup is generated
 * 
 * Usage:
 * 
 * var grid = new Ext.grid.GridPanel({
 *   colModel: //some column model,
 *   store   : //some store
 * });
 * 
 * Ext.ux.GridPrinter.print(grid);
