Added integrator_write_matrix routine to allow integrator matrices to be written out.
Modified integrator in PyGTK to output this matrix to a file in /tmp in the case where Integrator::solve fails.
Fixed a bug in densematrix_write_mmio.
The current implementation of integrator_write_matrix might not be quite right yet... needs some more thought.

Added simplified ASC_PANIC call that uses var-args, added throughout relation_util.c.
Fixed var_filter_t stuff in djex and fvex.
More assertions in integrator.c
Added output of initial state from lsode.c (hoping that's a good idea?)
Fixed output code from relman_diff2.
Added asc_panic_nofunc for non var-arg CPPs.
Disabled -O3 flag in building C++ API
Added __getitem__ and __getattr__ methods in Simuluation for simplified python syntax (eg M.x instead M.sim.x)
Integrator::analyse throws exceptions on error now.

Abstracted the internal integrator calls into a struct IntegratorInternals.
Fixed up compile-time list of integrators.
If IDA is not available, then 'INTEG_IDA' will not be defined.
Added ASC_ASSERT_RANGE for assertions x in [low,high).
Changed calling convention for integrator_get_engines().

Incorporated 'SolverParameters' functionality into 'Integrator', both at C level and C++/Python.
This shouldn't break Tcl/Tk as default parameters will be set and used invisibly.

Fixed Integrator::setEngine to throw range_error / IndexError on invalid selection.
Test suite contains testIDA that works now (more tests yet to come)

First tentative version in 'integration reporting':
Values of observed variables from the simulation are added to an Observer table after simulation completes.
This is not very efficiently coded at this stage but is a start.
Also some minor changes to text and comments in some base/generic files.

File length: 2465 byte(s)

Merged changes from DAE branch (revisions 702 to 819) back into trunk.
This adds the Integration API to the ASCEND solver (in base/generic).
Also provides pre-alpha support for 'IDA' from the SUNDIALS suite, a DAE solver.
Many other minor code clean-ups, including adoption of new 'ASC_NEW' and friends (to replace 'ascmalloc')
Added some very sketchy stuff providing 'DIFF(...)' syntax, although it is anticipated that this will be removed.
