+			@description Use this to safely attach arbitrary data to any DOM Element.
+			
+			This method is useful when you wish to avoid memory leaks that are possible when adding your own data directly to DOM Elements.
+			
+			When called with no arguments, will return glow's entire data store for the first item in the NodeList.
+			
+			Otherwise, when given a stringy key, will return the associated value from the first item in the NodeList.
+			
+			When given both a key and a value, will store that data on every item in the NodeList.
+			
+			Optionally you can pass in a single object composed of multiple key, value pairs.
+			
+			@param {String|Object} [key] The name of the value in glow's data store for the NodeList item.
+			@param {Object} [val] The the value you wish to associate with the given key.
+			@see glow.dom.NodeList#removeData
+			@example
+			
+			glow.dom.get("p").data("tea", "milky");
+			var colour = glow.dom.get("p").data("tea"); // milky
