[fusion-users] Widget Functions.

[Mike Adair]

Also, widgets must be associated with a DOM element to be instantiated.  
This can be either through a <Container><Item> element, or simply 
through a <div id='widgetName'> element in the page (I think this 
works).  You can try putting a breakpoint in the widget constructor to 
see if it ever gets instantiated.
