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