ripley now supports paso solvers again and returns an appropriate matrix type
id. Changed the getSystemMatrixTypeId() method to take a full SolverBuddy
instance and made some other simplifications.

moved SolverOptions to c++, split into SolverOptions for the options and SolverBuddy as the state as a precursor to per-pde solving... does break some use cases (e.g. pde.getSolverOptions().DIRECT will now fail, new value access is with SolverOptions.DIRECT), examples and documentation updated to match

Added dirac support to ripley, added interface for custom assemblers for ripleydomains (also added the custom assembler for 2D VTI waves), changed synthetic_VTI example to use the new, faster custom assembler

Used "new" raise syntax in a few places
Fixed some tabbing
Fixed some funnies involving changes to xrange/range
added a quick and nasty __hash__ function to Symbol
def __hash__(self):
return id(self)
This does mean that __hash__ and == do not match exactly. Not sure if that matters for our purposes

Add Boomer AMG as a new preconditioner
Can be used by .setPreconditioner(SolverOptions.BOOMERAMG)
and the following parallel coarsening method can be
used together with Boomer AMG preconditioner:
.setCoarsening(SolverOptions.CIJP_FIXED_RANDOM_COARSENING)
.setCoarsening(SolverOptions.CIJP_COARSENING)
.setCoarsening(SolverOptions.FALGOUT_COARSENING)
.setCoarsening(SolverOptions.PMIS_COARSENING)
.setCoarsening(SolverOptions.HMIS_COARSENING)
Note that Boomer AMG is only available when MPI is enabled.

Added/modified AMG tests:
- "self.failUnless(...)" became "self.assertTrue(...)"
because fail* is soon to be deprecated,
- fixed logical error in self.assertTrue argument,
- added another test, 'testSquare'.
Added some print statements to AMG.c in verbose mode to
identify which of the stopping conditions were fulfilled.
Changed default AMG parameters for 'setNumPreSweeps' and
'setNumPostSweeps' to 1 (huge speed improvment).
P.S Beware of bugs in the above code; I have only proved
it correct, not tried it... Jokes!

The MPI and sequational GAUSS_SEIDEL have been merged.
The couring and main diagonal pointer is now manged by the patternm which means that they are calculated once only even if the preconditioner is deleted.

This commit cleans up the incompressible solver and adds a DarcyFlux solver in model module.
Some documentation for both classes has been added.
The convection code is only linear at the moment.

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.

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.

The sparse solver can be called by paso now.
the building has been change to reduce some code redundancy:
now all scons SCscripts are importing scons/esys_options.py which
imports platform specific settings.
This form allows you to request diffs between any two revisions of this file.
For each of the two "sides" of the diff,
enter a numeric revision.
