/**
* Autoloader function.
*
* Loads classes "on the fly". Require or incluse statements are no longer needed.
* Class name should be the same as name of file where it is stored. Class files
* should have ".php" extension. Already known class paths are stored in special
* cache file. That cache file is stored in CACHE_DIR path, by default in
* SYS_DIR/cache, so that path should be writeable for apache. You can change that
* path in lms.ini file in directories section. You should clear cache file each
* time you move class file to another location.
*
* This function should be registered with spl_autoload_register function before
* first usage.
*
* @param string $class Class name
* @package LMS
