    Designed to clean the area when no players are present.
    Functions/scripts contained here are used as follows for the Area:

        OnEnter: [CheckForPC()]
            - Keeps track of the number of players in the area
        OnExit: [TimerCheck()]
            - Checks to see if any players remain in the area
            - Starts cleanup process when no PC is present
    * In addition the following script is needed:
        OnUserDefined: "area_clean_usr"
            - Performs the actual clearing of the area

    NOTE: The first two are presented as functions so that they can
        be easily incorporated with any existing area scripts.
