07-jun-2007 NvE Maximum OM id changed from 681 to 680 in IceRawTWR.cxx to ignore the signals
                of OM 681 which is always regarded is being bad.
                Also new OM slotname "READOUT" introduced in IceCal2Root, IceF2k and IceRawTWR
                to identify electrical, optical and digital readout based on the Dbase info
                and/or actual settings in the various data files (headers).
07-jun-2007 GdV OM readout type also updated from the data contents in IceRoot.cxx.
08-jun-2007 GdV Support introduced in IceRoot.cxx to set the waveform binsize based on the
                info from the data of the I3 file.
08-jun-2007 NvE First attempt for TWR ADC calibration in IceCal2Root.cxx.
09-jun-2007 GdV OM 681 now also ignored in IceRoot.cxx.
21-jun-2007 GdV Trigger device and "main" trigger introduced IceRoot.cxx to provide
                the actual trigger time(s).
21-jun-2007 NvE External stop and (first) trigger time taken into account for the
                TWR waveform timebins in IceRawTWR. This will provide a better
                synchronisation of the various waveforms and consequently of the
                extracted LE values.
