Detailed Description

Base class for concrete CSCChannelMapper classes that 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.

The original of this class, CSCChannelTranslator, was written in the expectation that one day it would be replaced by a full "cable map" stored in conditions data. That has not yet been required and so the mappings are hard-coded.

Concrete derived classes must implement the following:

Sort out any readout-flipping within the two endcaps for ME1a and ME1b strip channels.
If ME1a is ganged then map the ME1a channels from online labels 65-80 to offline 1-16.
Do nothing with wiregroup channels; the output = the input.
(Historically some test beam data needed wiregroup remapping but this was embedded directly in the Unpacker of CSCRawToDigi. We want to move any such mappings into this class rather than have them scattered through the code.)

Beware that if 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.
