// This is a helper class to build an identifing integer used by
// the simulation. It inherits from HitIdHelper, in order to get
// all the packing and shifting for free.
// The class is a singleton and a static GetHelper() is provided
// the constructor calls the Initialize() method which sets all the
// field dimensions
// Methods are provided to get access to the TRT Geometry
