    14  * Description:

    15  * This file defines an interface to an System Tone Service used by the

    16  * STS Server for playing and stopping tones.  Only one instance of this

    17  * class is created by the server, and it exists for the lifetime of the

    18  * server.  This class manages all of the active players, and guarantees

    19  * that the context values are unique.
