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