//  Description:
//    This is a messenger class to interface to exchange information
//    between Particle related classes and UI.
//
//  History:
//    13 June 1997, H. Kurashige   : The 1st version created.
//    10 Nov. 1997  H. Kurashige   : fixed bugs 
//    08 Jan. 1998  H. Kurashige   : new UIcommnds 
//    08 June 1998, H. Kurashige   : remove fProcessManagerMessenger
//    25 Nov. 1998, H. Kurashige   : add /particle/find
