Editor: This class can be used to automatically load classes in scripts located in multiple directories. When a class is loaded it scans a given lists of directories for class script files that start with the class name and have specific file name extensions. The class may exclude scanning given sub-directories. The class loads the class script file that is found in the scanned directories. The list of class scripts that is found may be cached in an INI file to avoid the overhead of scanning the search directories again when another class needs to be loaded.
