0005  * \class CSCChannelMapperPostls1
0006  *
0007  * A concrete CSCChannelMapper class to
0008  * map between raw/online channel numbers (for strips/cathodes and wires/anodes)
0009  * and offline geometry-oriented channel numbers, in which increasing number
0010  * corresponds to increasing local x (strips) or y (wire groups) as defined
0011  * in CMS Note CMS IN-2007/024.
0012  *
0013  * This version is for CMS Postls1 (2013-)
0014  *
0015  * 1. Sorts out readout-flipping within the two endcaps for ME1a and ME1b strip
0016  * channels. <BR> We do not yet know whether there WILL be any flipping. For now
0017  * we presume it is as in the Startup case. <BR>
0018  * 2. Doesnothing with ME1a channels since we intend each of the 48 strips to go
0019  * to 48 individual channels. <BR>
0020  * 3. Does nothing with wiregroup channels; the output = the input. <BR>
0021  *
0022  * Also note that the CSCDetId for ME11 and ME1b is identical. Offline we
0023  * presume ring=1 of station 1 to mean the ME1b strips. We use the identifier
0024  * ring=4 to denote the ME1a strips.
