/**
 * Original by Aaron Harun: http://aahacreative.com/2012/07/31/php-syntax-highlighting-prism/
 * Modified by Miles Johnson: http://milesj.me
 *
 * Supports the following:
 * 		- Extends clike syntax
 * 		- Support for PHP 5.3+ (namespaces, traits, generators, etc)
 * 		- Smarter constant and function matching
 *
 * Adds the following new token classes:
 * 		constant, delimiter, variable, function, package
