New Features as of version 1.02

  Copied the pretty.py Python module to the python area of the X-Midas
  option tree: it was previously missing

  Created an enumeration for DUAL_SOCKET and SINGLE_SOCKET so
  constructors (for MidasTalker, MidasServer, etc.) are easier to read
  and immediately see which mode you are using (both C++ and Python).

  Added a "dataReady" method to the C++ and Python MidasTalker:
  It allows users to poll a socket for data without actually
  having to read anything.  Implemented using a "dataReady_"
  method in MidasSocket_.

  Added two new global functions to the C++ and Python MidasTalker:
   * DistributedWaitForReadyMidasTalker
   * WaitForReadyMidasTalker
  These functions allow users to pass a list of MidasTalkers in
  and it will return a list of all MidasTalkers that are ready
  to return data.  This takes advantage of the "dataReady" method
  above.

  Fixed a bug in the M2k area: If the OpalPythonDaemon uses the
  Pickling Protocol 2, and tries to send an empty Multivector,
  a dynamic-cast would fail and stop the component.  Simple fix,
  an MV is forced to ALWAYS be a OpalTableImpl_GRAPHARRAY.
