31 //
32 // Class description:
33 //
34 // Simple placeholder for user Step limitations
35 // In order to activate these limitations, users need to register
36 // their "special" processes to each particle they want.
37 // Sample processes below can be found under processes/transportation
38 // MaxAllowedStep : UserStepLimit
39 // other limitation : UserSpecialCuts
40 // In addition, users can add their own Step limitations by creating
41 // new class derived from G4UserLimits. In these case, fType member
42 // is supposed to be used to identify class.
