 * Class uses all of vlibTemplate's functionality but debugs the template files.
 * Outputs a debug console to an html page, only use this for html files.
 *
 * NB: This class is not as well documented as the main vlibTemplate class as all
 * functions are private. This will be cleaned up in the future but it's quite
 * far down the priority list. It works, and right now, that's what counts.
