0003 /** \class L1MuGMTMerger
0004  *
0005  *  L1 Global Muon Trigger Merger.
0006  * 
0007  *  There are two GMT Mergers. One for the barrel (id=0) and 
0008  *  one for the forward (id=1) part.
0009  *
0010  *  The merger receives four DT(CSC) muons and four RPC muons.
0011  *  Each DT(CSC) muon is either merged with an RPC one or
0012  *  passed through.
0013  *
0014  *  To simplify the C++ model, the merger conatians also the conversion
0015  *  units and sort rank units as well as the MergeMethodSelection unit 
0016  *  which are separate units in the hardware.
0017  *
