First cut implementation of mesh.dump() using NetCDF.  TagMap not
saved yet.  The code for Points probably works but has not been tested.

The MPI branch is hereby closed. All future work should be in trunk.

Previously in revision 1295 I merged the latest changes to trunk into trunk-mpi-branch.
In this revision I copied all files from trunk-mpi-branch over the corresponding
trunk files. I did not use 'svn merge', it was a copy.

Had to undo commit to new MPI branch. The changes went into the original and
not the branch. The files committed here are exactly the same as revision 969.

Parallelization using MPI for solution of implicit problems.

Parallelization for explicit problems has already been accomplished in
the main SVN branch.

This is incomplete and is not ready for use.

changes to escript/py_src/pdetools.py and /escript/src/Data.h/.cpp to
make the Locator work in MPI. escript::Data::mindp now returns a 3 tuple,
with the MPI rank of the process on which the minimum value occurs
included. escript::Data::convertToNumArrayFromDPNo also takes the ProcNo
to perform the MPI reduction.

This had to be implemented in both the MPI and non-MPI versions to allow
the necesary changes to the Python code in pdetools.py. In the non-MPI
version ProcNo is set to 0. This works for the explicit scripts tested
thus far, however if it causes problems in your scripts contact Ben or
Lutz, or revert the three files (pdetools.py, Data.h and Data.cpp) to
the previous version.

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.
