0005  *  Handles the mapping between TCs and TTs.
0006  *  The mapping can be provided externally (via a mapping file)
0007  *  or can be derived on the fly based on the TC eta-phi coordinates.
0008  *  The bin boundaries need anyhow to be provided to establish the eta-phi coordinates
0009  *  of the towers (assumed as the Tower Center for the moment)
