Some modifications to the binary operations +,-,*/, pow.
The code is a bit simpler now and more efficient has there is
no reseising required now. the resizing method has been removed as
it is very, very inefficient. Even serial code should be faster now.
It is now forbidden to do an inplace update of scalar data object with an object
of rank >0 as this is very slow (and does not make much sense).

Tensor products for Data objects are now computed by a C++ method
C_GeneralTensorProduct, which calls C function matrix_matrix_product
to do the actual calculation.
Can perform product with either input transposed in place, meaning
without first computing the transpose in a separate step.

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.

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.

A few changes in the build mechanism and the file structure so scons can build release tar files:
* paso/src/Solver has been moved to paso/src
* all test_.py are now run_.py files and are assumed to be passing python tests. they can run by
scons py_tests and are part of the release test set
* escript/py_src/test_ are moved to escript/test/python and are installed in to the build directory
(rather then the PYTHONPATH).
* all py files in test/python which don't start with run_ or test_ are now 'local_py_tests'. they are installed i
by not run automatically.
* CppUnitTest is now treated as a escript module (against previous decisions).
* scons realse builds nor tar/zip files with relvant source code (src and tests in seperate files)
the python tests don't pass yet due to path problems.

+ NEW BUILD SYSTEM
This commit contains the new build system with cross-platform support.
Most things work are before though you can have more control.
ENVIRONMENT settings have changed:
+ You no longer require LD_LIBRARY_PATH or PYTHONPATH to point to the
esysroot for building and testing performed via scons
+ ACcESS altix users: It is recommended you change your modules to load
the latest intel compiler and other libraries required by boost to match
the setup in svn (you can override). The correct modules are as follows
module load intel_cc.9.0.026
export
MODULEPATH=${MODULEPATH}:/data/raid2/toolspp4/modulefiles/gcc-3.3.6
module load boost/1.33.0/python-2.4.1
module load python/2.4.1
module load numarray/1.3.3
