This sample illustrates using templates for a more complete and 
realistic scenario. 

It uses the NetFlix OData JSONP services as a source of data. 

This version of the movies sample demo uses the 
	$( targetSelector ).append( templateSelector, data ) 
pattern, and also uses the tmplCmd plugin and the rendered event.
