/**
* \class CSCChannelMapperStartup
*
* 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)
*
* 1. Sorts out readout-flipping within the two endcaps for ME1a and ME1b strip
* channels. <BR>
* 2. Maps the ME1a channels from online labels 65-80 to offline 1-16. <BR>
* 3. Does nothing with wiregroup channels; the output = the input. <BR>
*
* 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.
