 * chxavfilesystemwatcher.h
 * -------------------------
 *
 * Synopsis:
 * Encapsulates active object file system monitoring; watches a directory and
 * its children and executes an event handler when an event under that path
 * occurs
 * 
 * Intended to be used by a single class client (multiple client support should
 * be implemented by the event handler)
 * 
 * Target:
 * Symbian OS
 *
