35 // History:
36 // 02 Dec. 1995, G.Cosmo : Structure created based on object model
37 // 15 Feb. 1996, K.Amako : Implemented the 1st version
38 // 01 Jul. 1996, K.Amako : Hidden bin from the user introduced
39 // 26 Sep. 1996, K.Amako : Constructor with only 'bin size' added
40 // 11 Nov. 2000, H.Kurashige : use STL vector for dataVector and binVector
41 // 9 Mar. 2001, H.Kurashige : added PhysicsVector type and Retrieve
42 // 05 Sep. 2008, V.Ivanchenko : added protections for zero-length vector
43 // 19 Jun. 2009, V.Ivanchenko : removed hidden bin
44 // 02 Oct. 2013 V.Ivanchenko : Remove FindBinLocation method, use G4Log
45 //
