Components can (optionally) be given the nwAppId property on their 
inline constructors which will create a variable in the global 
namespace with the name specified in the attribute value and a 
reference to the component itself.

This means that if I create, say, a button, I can locate it via 
nwAppId like:


	<!-- in the HTML -->
	<div nwType="button" nwAppId="foo" />

	// in the JS:
	foo.componentType == "button";

Note: the variables that correpsond to components will only be 
(safely) available AFTER onLoad fires in the document.

Note 2: you can easily shoot yourself in the foot by giving multiple 
components the same nwAppId, since the last one will overwrite the 
reference set in earlier constructors. netWindows will internally 
give components unique Ids which can be used to locate components 
either from nodes or programatically. nwAppId is a circumvention of 
this system and therefore the uniqueness garuntees that NW would 
otherwise provide no longer apply.

Let me know if you need more information.
