escript/Data: Another fix for parallel var initialization. Also, the (error) return value of MPI_Gather was not used. I applied the same 'hack' as in other places in the file, namely declaring the variable beforehand but still ignoring the return value :-/

Two changes.

1. Move blocktimer from escript to esysUtils.
2. Make it possible to link to paso as a DLL or .so.

Should have no effect on 'nix's

In respect of 1., blocktimer had begun to spring up everywhere, so
for the moment I thought it best to move it to the only other library that
pops up all over the place.

In respect of 2., paso needed to be a DLL in order to use the windows intelc /fast
option, which does aggressive multi-file optimisations. Even in its current form, it either
vectorises or parallelises  hundreds more loops in the esys system than appear in the pragmas.

In achieving 2. I have not been too delicate in adding

PASO_DLL_API

declarations to the .h files in paso/src. Only toward the end of the process of
the conversion, when the number of linker errors dropped below 20, say, did I choosy about what
functions in a header I declared PASO_DLL_API. As a result, there are likely to be many routines
declared as external functions symbols that are in fact internal to the paso DLL. 
Why is this an issue?  It prevents the intelc compiler from getting aggressive on the paso module.
With pain there is sometimes gain. At least all the DLL rules in windows give good
(non-microsoft) compiler writers a chance to really shine.

So, if you should see a PASO_DLL_API on a function in a paso header file,
and think to yourself, "that function is only called in paso, why export it?", then feel free to
delete the PASO_DLL_API export declaration.

Here's hoping for no breakage.....

Modified Data::toString() so it doesn't throw on DataEmpty.
Added setEscriptParamInt and getEscriptParamInt as free functions.
At the moment all they do is allow you to set the param TOO_MANY_LINES.
This is used to determine when printing a Data object will show you the 
points and when it will print a summary.

I've set the default value back to 80 lines.
If you need to see more lines use (in python):

setEscriptParamInt("TOO_MANY_LINES",80000)

All about making DataEmpty instances throw.
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

Exposed getDim from AbstractDomain to python to fix bug.

Added isEmpty member to DataAbstract to allow it to throw is queries are 
made about a DataEmpty instance.


Added exceptions to DataAbstract, DataEmpty and Data to prevent calls 
being made against DataEmpty objects.
The following still work as expected on DataEmpty instances

copy, getDomain, getFunctionSpace, isEmpty, isExpanded, isProtected, 
isTagged, setprotection.

You can also call interpolate, however it should throw if you try to 
change FunctionSpaces.

implementation of the compy methods.

In VC++ boost has problems with numarray arguments from python. This

escript data objects can now be saved to netCDF files, see http://www.unidata.ucar.edu/software/netcdf/.
Currently only constant data are implemented with expanded and tagged data to follow.
There are two new functions to dump a data object

   s=Data(...)
   s.dump(<filename>)

and to recover it

   s=load(<filename>, domain)

Notice that the function space of s is recovered but domain is still need. 

dump and load will replace archive and extract.

The installation needs now the netCDF installed.

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.

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).

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.

coordinates, element size and normals returned by corresponding
FunctionSpace mesthods are now protected against updates. So 
+=, -=, *=, /=, setTaggedValue, fillFromNumArray will through an

The FunctionSpace class does nut buffer the oordinates, element size and
normals yet.

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.
