// Class description:
//
// This class represents the Messenger that defines the G4UI macro commands
// allowing the user controlling an adjoint/reverse MC simulation. It calls
// methods of G4AdjointSimManager.
//
// 1) Start an adjoint simulation
// ---------------------------------------------------
// Command:
//  -/adjoint/start_run nb: Start an adjoint simulation with a number of
//                          events given by nb.
// 2) Definition of the external source
// ---------------------------------------------------
// The external source represents the real external source of particles till
// which adjoint particles are tracked in the reverse tracking mode of the
// simulation (see G4AdjointSimManager.hh and G4Application Developer guide for
// more infos). The user can define the source as the external surface of a
// sphere or of G4 volume of the geometry. He can also set the maximum energy
// of the source. If an adjoint particle get an energy higher than this maximum
// energy before reaching the external surface source it is killed without
// being registered.
// Commands:
//  -/adjoint/DefineSphericalExtSource R X Y Z unit_length
//   The external source is set on a sphere with radius R and centered on
//   position (X,Y,Z)
//  -/adjoint/DefineSphericalExtSourceCenteredOnAVolume pvol_name R unit_length
//   The external source is set on a sphere with radius R and with its center
//   position located at the center of the physical volume specified by the
//   name pvol_name.
//  -/adjoint/DefineExtSourceOnExtSurfaceOfAVolume pvol_name
//   The external surface is set as the external boundary of a the physical
//   volume with name pvol_name.
//  -/adjoint/SetExtSourceEmax Emax energy_unit
//   Set the maximum energy of the external source.
//
// 3) Definition of the adjoint source
// ---------------------------------------------------
// The adjoint source represents the source from which adjoint primary
// particles are generated (see G4AdjointSimManager.hh and G4Application
// Developer guide for more infos).
// The user can define the source as the external surface of a sphere or of
// G4 volume of the geometry. He sets the minimum maximum energy of the
// source and defines which type of adjoint primary particles should be
// considered.
// Commands:
//  -/adjoint/DefineSphericalAdjSource R X Y Z unit_length
//  The adjoint source is set on a sphere with radius R and centered on
//  position (X,Y,Z)
// -/adjoint/DefineSphericalAdjSourceCenteredOnAVolume pvol_name R unit_length
//  The external source is set on a sphere with radius R and with its center
//  position located at the center of the physical volume specified by the
//  name pvol_name.
// -/adjoint/DefineAdjSourceOnExtSurfaceOfAVolume pvol_name
//  The external surface is set as the external boundary of a the
//  physical volume with name pvol_name
// -/adjoint/SetAdjSourceEmin Emin energy_unit
//  Set the minimum energy of the external source
// -/adjoint/SetAdjSourceEmax Emax energy_unit
//   Set the maximum energy of the external source
// -/adjoint/ConsiderAsPrimary particle_name
//  The type of particle specified by  "particle_name" will be added in
//  the list of primary adjoint particles. The list of candidates depends on the
//  reverse physics processes considered in the simulation. At the most the 					potential
//  candidates are (e-, gamma, proton, ion).
// -/adjoint/NeglectAsPrimary particle_name
//  The type  of particle specified by  "particle_name" will be removed
// from the list of primary adjoint particles. The list of candidates depends
// on the reverse physics processes considered in the simulation. At the most
// the potential candidates are (e-, gamma, proton, ion).
