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 Startup (2008-2013)

Sorts out readout-flipping within the two endcaps for ME1a and ME1b strip channels.
Maps the ME1a channels from online labels 65-80 to offline 1-16.
Does nothing with wiregroup channels; the output = the input.

Since ME1a is ganged, the 48 strips in ME1a are fed to 16 channels, so it is important to distinguish the nomenclatures "strip" vs "channel". It is usually a meaningful distinction!

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.
