New Features as of Version 0.82

  Using OpenContainers 1.5.2
   -Fixed a bug with swap on AVLNR so that Sorted Iteration works
   -Made operator() on AVLHashT, AVLTreeT and HashTableT to be const
   -Added #ifndef protections to ocstringtools.h
   -Included ocstringtools.h in ocvalreader.h 

  Fixed a Pickling problem that occurs when Pickling 
  a Numeric Array:  It may be fixed here, but make sure
  your applications picks up the new code for the fix
  (SSGS 2.22.1 does not have the fix yet, so don't try
  to use Numeric with that version of SSGS).  This means
  either getting the new Midas 2k tree (with the fix
  in the M2k directory) or getting the new m2pythonpickler.{h,cc}
  files in your C++ code (from the C++ directory).

  Changes to ptools X-Midas option tree organization:  
  (these two changes have NO EFFECT to non X-Midas users)

    (1) Based on user feedback, moved all files in ptools/inc/oc into just
    the inc directory so there is no need to add the extra -I (in
    your primitives.cfg) into the oc directory. 

    (2) Also, we are separating the ptools library (which was just
    one library) into two libraries: oc and ptools.  The oc library
    contains the stuff needed to link only the OpenContainers libraries,
    and the ptools libraries.   This shouldn't affect anyone,
    as ptools depends on oc library. (But this gives added flexibility
    to those who just want the oc functionality to just link against
    that library)
