New features as of version 0.90

  Augmented the OpalTable reader for C++ so that when it reads
  in an OpalTable with all keys 0..n, it will turn it into
  an Arr.  I.e., OpalTable {"0":D:1, "1":D:2 } becomes [1,2].
  You can choose to preserve the "tableness" of the OpalTable,
  but the default will be to become an Arr.  This was done so
  that ASCII OpalTables convert to Tabs and back without 
  losing too much information.  (The "Pickling" transformations
  do not have this problem).
   -Added the "ReadValFromOpalfile" routine, which can handle
    the embedded Array-like OpalTables, and updated opal2dict
    to use that routine instead.
   -expectTab now returns a flag indicating whether or not
    it could be converted to an Arr
   -expectAnything has a flag to indicate whether or not to
    convert from Tab to Arr:  by default it does.

  Added the MidasYeller and MidasListener:  A UDP server and
  client that "feel like" the MidasServer and MidasTalker.
  This is a preliminary version that should work, but will have
  expanded functionality in the future.  Modified the MidasSocket_
  to factor some common code from all the Midas* classes.
  The MidasYeller and MidasListener have both a Python and C++
  version, and should be interchangable.  

  In restructuring MidasSocket_ (see above), added helper functions to
  the .cc of the MidasSocket_ which allows the C++ Midastalker
  to be completely inline (i.e., removed the midastalker.cc file).
  Moved a lot of the name server querying and socket creation
  to MidasSocket_. 

  Added 'close' method as an alias for "cleanUp" in all
  the Python and C++ Midastalker and MidasServer code.
  
  Added the opalfile Python module.  This is a fairly complete
  Python module that allows manipulation of OpalTables and Opal files,
  but currently requires the Python "Numeric module".
  This is a natural addition since we can manipulate OpalTables
  within C++ in earlier releases.  This is just the 'opalfile'
  module from XMPY.  Future releases will have remove the
  Numeric dependance.

  Allowed possibility of a timeout in the "open" of the
  MidasTalker (both Python and C++) so that when the socket
  protocol (dual or single socket), a timeout can occur can
  really occur so a Midastalker won't hang on open.

  Added some new examples to the C++, Python and X-Midas
  area to show how the MidasYeller and MidasListener work.
