// Original Author : Haryo Sumowidagdo <Suharyo.Sumowidagdo@cern.ch>
// Purpose         : Hold on to eta-dependent resolution.
//                   Return Vector_Resolution as a function of eta.
//                   Does not assume symmetry between +/- eta.
//                   The interpretation of eta (physics or detector) is
//                   left to user's implementation.
