  /**
   * \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.
