New Features as of version 0.85

  Added C++ routines to allow to convert from OpalTables in literal
  (i.e., text) format to Tabs.  The OpalReader class
  and support routines are in opalutils.h:
   -ReadTabFromOpalfile
  
  Added C++ routines to write Tab files as Opaltables.
  The main routine in opalprint.h:
   -prettyPrintOpal(Val&v, ostream& os)

  Added some new test utilities to convert to/from Opaltables/Tab.
   -opal2dict: convert from text file with Opaltable 
               to text file of Python dictionary
   -dict2opal: convert from text file containg Python Dictionary (Tab)
               to text file with an Opaltable

  Updated to opencontainers 1.5.4. New bugs and feature fixes:
   -Fixed a bug where very large integers would truncate to 0 when
    reading from literals (files or strings).
   -Floating point quantities will always output a decimal point
    when printed as a literal so you can differentiate between
    '1' and '1.0' (as an int_4 and real_8 respectively) when
    looking at input strings/files.  
   -Added the ability of Tabs and Arrs to have an extra ,
    when specifying literals (instead of a syntax error)

  Updated the X-Midas ptools option tree to contain opencontainers 1.5.4,
  as well as adding the new Python<->OpalTable libraries.
