Another bugfix in efficiency computation task, plus some changes in macros

//
// *** Class AliRsnCutValue ***
//
// This cut implementation can be used to cut generically on
// any value which can be computed from AliRsnValue class.
// Since that value is implemented always as a Double_t one,
// then this cut operates only with the Double_t data members
// of the AliRsnCut base class.
// It allows to cusomize the reference AliRsnValue object by
// means of a getter that returns a pointer to it.
// This cut can apply to any kind of object, but the type of
// target must be one of those for which the chosen value type
// makes sense to be computed
