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.

Added canTag methods to FunctionSpace and AbstractDomain (and its 
offspring).
This checks to see if the domain supports tags for the given type of 
function space.

Constructors for DataTagged now throw exceptions if you attempt to make 
a DataTagged with a FunctionSpace which does not support tags.
To allow the default constructor to work, NullDomain has a single 
functioncode which "supports" tagging.

Fixed a bug in DataTagged::toString and DataTypes::pointToString.

Added FunctionSpace::getListOfTagsSTL.

algorithm(DataTagged, BinaryFunction) in DataAlgorithm now only 
processes tags known to be in use.
This fixes mantis issue #0000186.

Added comment to Data.h intro warning about holding references if the 
underlying DataAbstract changes.

_python_ unit tests have been updated to test TaggedData with invalid 
FunctionSpaces and to give the correct answers to Lsup etc.

Added Data::copySelf() [Note: this is exposed as copy() in python].
This method returns a pointer to a deep copy of the target.
There are c++ tests but no python tests for this yet.

All DataAbstracts now have a deepCopy() which simplifies the 
implementation of the compy methods.

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.

The set/getRefVal functions of Data objects have been removed (mainly to avoid later problems with MPI).
Moreover, a faster access to the reference id of samples has been introduced. I don't think that anybody will
profit form this at this stage but it will allow a faster dump of data objects.

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.

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).
