Remove hardwired hososcope numbers in THcHallcSpectrometer
    Hardwired numbers are fixed in THcHallcSpectrometer class.
    Generalized functions for center of hodoscope planes and
    their spacings are defined.
Fix problem with uninitialized variables used in THcHodoscope::Clear
THcHodoscope::Clear is called at beginning of analysis before ReadDatabase and Init methods
and therefore  MAXHODHITS and fNPlanes are uninitiated.
Change Clear to ClearEvent
Add call to ClearEvent in Decode
Eliminate Clear method in THcHodoscope.h
Add "+1" to length when using new char[]
Found when doing valgrind --tool=memcheck --track-origins=yes --leak-check=full hcana
Return errors like below

Initialize arrays in constructors.  Delete them in destructor.
  Use InitArrays method in THcCherenkov and THcAerogel
  Null out all array pointers in the InitArrays method and
  call that method from all constructors so that it is always
  safe to delete these arrays.
Remove fADCHits (a TClonesArray) from DeleteArrays and InitArrays
Add [fNLayers] in THcShower.h for proper filling
Don't access time_pos[i] and time_neg[i] if not defined.
Escape the cd command for people that have weird aliases of cd.
Remove unnecessary TMath::Nint() calls to fix compile error

- no need to call Nint() on an integer
Minor memory leak squashing.  (From running valgrind)
Restore default THcDriftChamber constructor.
Disable hms track debug info

debug info should be suppressed in the main develop branch
Get rid of some warnings and excess couts
