34 // Class description:
35 //
36 // A physics vector which has values of energy-loss, cross-section,
37 // and other physics values of a particle in matter in a given
38 // range of the energy, momentum, etc. The scale of energy/momentum
39 // bins is in logarithmic.
40 
41 // History:
42 // 02 Dec. 1995, G.Cosmo : Structure created based on object model
43 // 03 Mar. 1996, K.Amako : Implemented the 1st version
44 // 27 Apr. 1996, K.Amako : Cache mechanism added
45 // 01 Jul. 1996, K.Amako : Hidden bin from the user introduced
46 // 26 Sep. 1996, K.Amako : Constructor with only 'bin size' added
47 // 11 Nov. 2000, H.Kurashige : Use STL vector for dataVector and binVector
48 // 16 Aug. 2011 H.Kurashige : Move dBin, baseBin to the base class
49 // 02 Oct. 2013 V.Ivanchenko : Remove FindBinLocation method
