Modify THcFormula and THcParmList to match changes to THaFormula
     (needed for reports)
  Small changes in THcInterface and detector classes for compatibility
     with new OO decoder and podd 1.6

  For the most part this is making sure that the loop variable in
  a for loop is of the same type as the variable that it is compared
  against (Often a UInt_t).

  Don't put [1] at end of variable name as is done with
  numerical parameters with Define.

  Use new CCDB methods to get table row and column counts

  Title now copied to THcParmList variable
  String variables copied.  (Only first element of string array copied)
  Parameter created as int or double depending on CCDB table type
  Multiple column tables ignored.

  CCDB must be installed and CCDB_HOME defined before compiling.
  If CCDB_HOME is not defined, hcana is compiled without CCDB support
  scons has not been updated to compile with CCDB support
  To use, instead of gHcParms->Load(filename), do
    gHcParms->OpenCCDB(runnum, ccdb_connection_string)
    gHcParms->LoadCCDBDirectory("hms","h")
    gHcParms->LoadCCDBDirectory("sos","s")
    gHcParms->LoadCCDBDirectory("gen","g")
  Parmaters will be loaded into the same internal gHcParms list as with
  ThcParmList::Load, so no changes to detector classes are needed.
  Scripts to convert existing parameters into CCDB are under development.
  Currently all ccdb constants are loaded as doubles as there is not
  a way to easily query ccdb to get the data type.
  Also strings are not loaded.

These were related to a) scope of some variable declarations, and b) use
of pre-increment vs. post-increment of non-primitive types (this has a
slight performance hit due to the way that pre- vs. post-increment
operators are overloaded in C++.

Also cleaned up a few places where initialized variables were not being
used.

  Use HALLC_MODS in make file to turn on Hall C changes in Podd.
  Remove unneeded and now broken includes of THaDB.h.

Use DBRequest inside of loops over planes, using Form
to construct variables names that have the plane lable in them
(e.g. 1x, 1y, 2x, 2y)

prepended to all variables in the DBRequest list.

detector parameters from the gHcParms (THcParmList).

use the run number to determine which parameter and map files to use.

string variables from the Hall C style parameter files.  String
variables are loaded into a THaTextvars object that is held in the
THcParmList object.  PrintFull will now print all the string variables
as well as the numerical variables.  Added GetString, AddString and
RemoveString methods to access and modify the string variables.

that includes a class to read CTP style parameter files.
