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.

As the LinearPDE uses coefficients as reduced even if they are handed
over as full the projector runs into a problem when reduced and full
arguments are used in the same projector. Now the projector resets the
coefficients befor starting the projection.

The modification fixes a problem with the garbage collection in python. 
The problem seems that a default value of a method argument is seen as
being dependend on the the instance of the class. This produces a
circular dependence and can stop the garbage collection to delete the
object. The situation becomes in particulary bad if the class provides a
__del__ method as it is not clear where to break the circle.

We need to revisit all python classes in escript & Co to remove this
possible problem.

I have done some clarification on functions that allow to access individual data point values in a Data object. 
The term "data point number" is always local on a MPI process and referes to the value (data_point_in_sample, sample)
as a single identifyer (data_point_in_sample + sample * number_data_points_per_sample). a "global data point number"
referes to a tuple of a processour id and local data point number.

The function convertToNumArrayFromSampleNo has been removed now and convertToNumArrayFromDPNo renamed to getValueOfDataPoint.
There are two new functions:

   getNumberOfDataPoints
   setValueOfDataPoint

This allows you to do things like:

  in=Data(..)
  out=Data(..)
   for i in xrange(in.getNumberOfDataPoints())
       in_loc=in.getValueOfDataPoint(i)
       out_loc=< some operations on in_loc>
       out.setValueOfDataPoint(i,out_loc)


Also mindp  is renamed to  minGlobalDataPoint and there is a new function getValueOfGlobalDataPoint. While in MPI the functions getNumberOfDataPoints and getValueOfDataPoint are working locally on each process (so the code above is executed in parallel).
the latter allows getting a single value across all processors.

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.

Large number of changes to Finley for meshing in MPI.

- optimisation and neatening up of rectcanglular mesh generation code
- first and second order 1D, 2D and 3D rectangular meshes are now
  available in finley and escript using MPI.
- reduced meshes now generated in MPI, and interpolation to and from 
  reduced data types now supported.
