<?php

   See working example at http://superprivate.com/dtest.php

   debugger.php -- debugging messages with varying verbosity
   usage:
         debug->add_message($message, $loglevel, __LINE__, __FILE__);
         debug->report($threshhold);       

When you put debug messages in your code, you should mark them as level 0 if
they are very important. If they are only notices or not very important, mark them with
a higher number. 

The debug report($threshhold) function will show you all debug messages 
that are marked with a number less than the $threshhold you ask for.
