Changes relating to the MPI version of escript
The standard OpenMP version of escript is unchanged

- updated data types (Finley_Mesh, Finley_NodeFile, etc) to store meshes
  over multiple MPI processes.
- added CommBuffer code in Paso for communication of Data associated
  with distributed meshes
- updates in Finley and Escript to support distributed data and operations
  on distributed data (such as interpolation).
- construction of RHS in MPI, so that simple explicit schemes (such as
  /docs/examples/wave.py without IO and the Locator) can run in MPI.
- updated mesh generation for first order line, rectangle and brick
  meshes and second order line meshes in MPI.        
- small changes to trunk/SConstruct and trunk/scons/ess_options.py to
  build the MPI version, these changes are turned off by default.
