1) Read-in of the trigger reference time cuts was in ReadDatabase method
  when it should be in Init method. Moved to the Init method before
  call to InitHitList where the reference cuts are used.

2) Modified the selection of the good TDC hit for filling the TdcTimeRaw
and TdcTime. Previosly used the TdcTime but not picks the TDC hit with the TdcTimeRaw that is within
the time min and max windows that can be set by parameters. Default windows are min=0 and max=10000.
If two hits in the time window then selects last hit within window.
If not hits within time window then TdcTimeRaw=0 and TdcTime=0.
The TdcMultiplicity is always filled.

1) THcTrigDet
   a) Modify code to use string vector fTrigNames to identify which of the trigger
     trigger detector TDC signals to use for coincidence timing. This
      replaces the hard-coded names. The integer array fTrigId[4] keeps
     track of the array ID in the overall fTDcNames vector that goes
      with the fTrigNames[4]
   b) The fTrigNames must be in order of SHMS ROC1, HMS ROC1, SHMS ROC2
     and HMS ROC2.
   c) Default names are "pTRIG1_ROC1","pTRIG4_ROC1","pTRIG1_ROC2","pTRIG4_ROC2"
      The parameter is t_coin_trigNames
      For example:
      t_coin_trigNames="pTRIG1_ROC1 pTRIG4_ROC1 pTRIG1_ROC2 pTRIG4_ROC2"
      This parameter is read-in and the split into a string vector fTrigNames.
   d) In HcTrigDet::ReadDatabase , all members of fTrigID array are set
to -1 then a loop over all Tdc in the trigger detector looks for match between
fTdcNames amd fTrigNames to set fTrigId. If match not found the fTrigId = -1.
   e) In THcTrigDet.h made new method Get_CT_TrigTime(Int_t ii) to be used
in in THcCoinTime to get the 4 trigger times: SHMS ROC1 (ii=0), HMS ROC1 (ii=1),
SHMS ROC2 (ii=2) and HMS ROC2 (ii=3).  If fTrigId[ii]=0 then it returns 0
otherwise returns fTdcTime[fTrigID[ii]].

2) THcCoinTime
  a) Previously used the raw trigger times and had a hard-coded 0.1 ns/channel
conversion. Now use the trigger times which already are in ns using the
ns/channel conversion set in the TrigDet.
  b) Now use the new TrgiDet method Get_CT_TrigTime(ii) to get the
trigger times for SHMS ROC1, HMS ROC1, SHMS ROC2 and HMS ROC2.

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.
