Testing the template_context_prerender hook

Browse Source 
This allows for modifying any context *right before render*, including
access to the variables that are passed in.  This test takes advantage
of that and takes one of the variables, "doubleme", and modifies
it (doubles it!)

In our case it turns "happy" and "joy" into "happyhappy" and "joyjoy".
