// Class description:
//
//    A physics ordered free vector inherits from G4PhysicsVector 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.). In addition, the ordered free vector provides a method for
//    the user to insert energy/value pairs in sequence.  Methods to
//    Retrieve the Max and Min energies and values from the vector are
//    also provided.
