/*** NZVLE TODO
 *** 
 *** + Break the html/css bits of the default template into separate files
 ***   they mess up the code layout and indentation, and generally don't 
 ***   belong here.
 *** + Clean up and document the calling conventions -- get rid of $parameter
 *** + the callbacks to template_variables_substitute are *evil* -- rework
