// 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, i.e. it is NOT need to be linear or log. Only
// restriction 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.
 
// Authors:
// - 02 Dec. 1995, G.Cosmo: Structure created based on object model
// - 06 Jun. 1996, K.Amako: Implemented the 1st version
// Revisions:
// - 11 Nov. 2000, H.Kurashige: Use STL vector for dataVector and binVector
// - 04 Feb. 2021, V.Ivanchenko moved implementation of all free vectors 
//                 to this class
