Detailed Description

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.
   We do not yet know whether there WILL be any flipping. For now we presume it is as in the Startup case.
   
2. Doesnothing with ME1a channels since we intend each of the 48 strips to go to 48 individual channels.
   
3. Does nothing with wiregroup channels; the output = the input.
   

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.
