//      GEANT 4 class header file

//  G4PhysicsFreeVector.hh
//
//  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 free, ie. it is NOT need to be linear or log. Only 
//    restrication is that bin values alway have to increase from
//    a lower bin to a higher bin. This is necessary for the binary
//    search to work correctly.

//  History:
//    02 Dec. 1995, G.Cosmo : Structure created based on object model
//    06 Jun. 1996, K.Amako : Implemented the 1st version
//    01 Jul. 1996, K.Amako : Cache mechanism and 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
//    02 Oct. 2013  V.Ivanchenko : Remove FindBinLocation method
