36// History:
37// 02 Dec. 1995, G.Cosmo : Structure created based on object model
38// 15 Feb. 1996, K.Amako : Implemented the 1st version
39// 01 Jul. 1996, K.Amako : Hidden bin from the user introduced
40// 26 Sep. 1996, K.Amako : Constructor with only 'bin size' added
41// 11 Nov. 2000, H.Kurashige : use STL vector for dataVector and binVector
42// 9 Mar. 2001, H.Kurashige : add PhysicsVector type and Retrieve
43// 05 Sep. 2008, V.Ivanchenko : added protections for zero-length vector
44//
