Cleaned up code comments in units.h
Fixed a bug with starting timesteps in LSODE (i think)
Added function to output a SampleList to the console (for debugging)
Removed debug output from base/generic/test/SConscript.
Removed 'custom' headers for UnitsM in ascpy.i
Made a sane default ctor for UnitsM
Added some more test cases to the Python unittest suite (still a problem running multiple solver-based tests in a single run)

Adding more LSODE test cases.
Removing some 'error tree' debug output.

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.

Some success with IDA: fixed up the indexing dilemma and was able to
integrate 'johnpye/thermalequilibrium.a4c' for a short time span (but
through to 3000 s as with LSODE). I would blame lack of jacobian routine
in the first instance.

Added 'more properties' button in Properties dialog for a variable, to allow
values of ode_id, ode_type etc to be queried (but not changed).

- fixed a minor bug in the use of dimensions in samplelist
and a #define misuse in ospath.
- defined eolstyle unix on the trunk, as I have encountered
at least 4 too many mixed-eol-style-in-one-file files in trying to 
rebuild today. obviously committer discipline is insufficient.

File length: 30015 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.
