* Implement an autoloader When cleaning up classes for psr2, things got a bit unwieldy, so I implemented a class autoloader. I created a PSR-0 compliant LibreNMS directory and moved all classes there that made sense. Implemented LibreNMS\ClassLoader which supports adding manual class mappings This reduces the file includes needed and only loads classes when needed. * Add teh autoloader to graph.php * Add a small bit of docs Fix incomplete class in includes/discovery/functions.inc.php
