// Enum TG4StepStatus
// ------------------
// In orded to take into account different stepping 
// mechanism in G3 and G4 three states of TG4StepManager
// are defined:
//  kVertex     - returns track properties in the vertex
//                position before particle started stepping
//  kBoundary   - returns track properties when particle
//                is crossing geometrical boundary
//                (the volume that preceeds the boundary is returned
//                 as current volume)
//  kNormalStep - returns track properties in a post step
//                point
