// Enum TG4G3Cut
// -------------
// Enumeration for G3 types of physics processes controls.
// The G4 physics processes and particles which the process
// control is applied to are indicated in the comments.
// The process control is mapped to the physics processes
// (using TG4ProcessControlMap) at the moment of process creating
// by the physics constructor; the physics contructor type
// is indicated by the "Physics:" comment.
