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

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

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

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

 * that the context values are unique.
