//
//  Class description:
//
//    A physics vector which has values of energy-loss, cross-section, 
//    and other physics values of a particle in matter in a given 
//    range of the energy, momentum, etc. The scale of energy/momentum
//    bins is in logarithmic.

//  History:
//    02 Dec. 1995, G.Cosmo : Structure created based on object model
//    03 Mar. 1996, K.Amako : Implemented the 1st version
//    27 Apr. 1996, K.Amako : Cache mechanism added
//    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
//    16 Aug. 2011  H.Kurashige : Move dBin, baseBin to the base class
//
