// ------------------------------------------------------------
//  GEANT 4 class header file 
//
//  History: first implementation, based on object model of
//  2nd December 1995, G.Cosmo
//   ----------------  G4ProcessManager  -----------------
// Class Description 
//  It collects all physics a particle can undertake as seven vectors.
//  These vectors are 
//   one vector for all processes (called as "process List")
//   two vectors for processes with AtRestGetPhysicalInteractionLength
//                                    and AtRestDoIt
//   two vectors for processes with AlongStepGetPhysicalInteractionLength
//                                    and AlongStepDoIt
//   two vectors for processes with PostStepGetPhysicalInteractionLength
//                                    and PostStepDoIt
//  The tracking will message three types of GetPhysicalInteractionLength
//  in order to limit the Step and select the occurence of processes. 
//  It will message the corresponding DoIt() to apply the selected 
//  processes. In addition, the Tracking will limit the Step
//  and select the occurence of the processes according to
//  the shortest physical interaction length computed (except for
//  processes at rest, for which the Tracking will select the
//  occurence of the process which returns the shortest mean
//  life-time from the GetPhysicalInteractionLength()).
//
// History:
// revised by G.Cosmo, 06 May 1996
//    Added vector of processes at rest, 06 May 1996
// ------------------------------------------------------------
//   New Physics scheme           8 Jan. 1997  H.Kurahige
//   Add SetProcessOrdering methods     27 Mar 1998  H.Kurahige
//   Add copy constructor (deep copy)   28 June 1998 H.Kurashige
//   Add GetProcessActivation     3 May. 1999 H.Kurashige
//   Use STL vector instead of RW vector    1. Mar 00 H.Kurashige
//   Modify G4ProcessVectorOrdering to fix FindInsedrtPosition 15 Feb. 2005
