1) Created Coincidence Time Physics Module
2) Created method to get coin. trig times in the THcTrigDet.cxx class

1) Have time cut on TrigDet reference time for TDC and ADC,
       to select reference time from multiple hits

2) Have time window to select best TDC or ADC reference time subtracted
   time  hit for each channel.

  So that the counts can be reported in report files.

  Add End method to each detector that calls MissReport which
  prints the number of events with missing TDC and ADC reference times.

   For a TrigDet associated with one spectrometer, call SetSpectName
   so that H.present or P.present can be found.
   For coin TrigDet, supply a list of event types for which warnings
   should be suppressed.

  To do this suppression, a trigger detector object needs to know the
  name of spectrometer it is associated with.  By default it will get
  this name from the first character of the it's own name.  This can
  be overridden with the SetSpectName method.

In HcTrigDet::Init moved InitHitList after gHcDetectorMap->FillMap so that the refindex can be filled for the trigger TDC modules
In ReadDatabase add parameters fTdcOffset and fTdcChanperNS
In Decode set fTdcTime[cnt] = rawTdcHit.GetTime()*fTdcChanperNS-fTdcOffset
Ths makes the time into a positive number wiht units of ns
Need to add the parameter to either thms.param or tshms.param or
it will use defaults of 0.1 and 300.
Need to eventually get the fTdcChanperNS from event 125.

`THcTrigRawHit` now uses raw ADC and TDC classes.
Added new leaves to the `THcTrigDet` Root output.

As it turns out, this was not so easy fix. I had to do:
- add at least c++0x support to scons (works for g++ 4.4.7!)
- change how my DefineVariables works

The c++0x support is bonus, since now we can use some additional features, like auto keyword (see https://gcc.gnu.org/gcc-4.4/cxx0x_status.html).

Modified THcTrigRawHit.
Modified THcTrigDet.
Updated documentation.
