/**
 * Simple URL ReWrite (experimental) //TODO test, discuss, benchmark, enhance and include in eFront etc. if all goes well.  
 * Why?: 
 * - To make simple url rewrites as quick and easy for plugin developers to implement as it currently is to do the same with .htaccess 
 * - To use the same familiar standard as used by e_cron, e_status, e_rss etc. etc. so even a novice developer can understand it. 
 * 
 * @example (.httaccess): 
 * RewriteRule ^ref-(.*)/?$ e107_plugins/myplugin/myplugin.php?ref=$1 [NC,L] 
 * 
 * @example (e_url.php file - in the 'myplugin' folder)
 * 
 *	class myplugin_url // plugin-folder + '_url'
