//    15 Feb. 1996, K.Amako : Implemented the 1st version
//    01 Jul. 1996, K.Amako : Hidden bin from the user introduced
//    26 Sep. 1996, K.Amako : Constructor with only 'bin size' added
//    11 Nov. 2000, H.Kurashige : use STL vector for dataVector and binVector
//    9  Mar. 2001, H.Kurashige : add PhysicsVector type and Retrieve
