A function to clean an item from a dojox.data.JsonRestStore without sending a delete req to the server

unCacheItem.js

		unCacheItem: function(item){
			// summary:
			//		deletes item and any references to that item from the store.
			//		No request will be issued serverside
			//		extend dojox.data.JRS, and put this function in
			//	item:
			//		item to delete
			//

			//	If the desire is to delete only one reference, unsetAttribute or
			//	setValue is the way to go.
