      - Description: TBID is a test beam cell ID class that provides a unique integer for each cell in the combined
                Beam Test of 2002. This class can be used in two different ways. In the first way the class holds as a
                member, the cells ID, which is created when the object is constructed or alternatively it can be used as
                a tool for converting between detector ID and the various integer coordinates (idet,ieta,iphi,iz).  
                In the second case the constructor which takes no parameters is used.
