/**
* @class GetIt.GridPrinter
* @author Ed Spencer (edward@domine.co.uk)
* 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);
*
