Trying to debug fprops_triple_point for Toluene with pengrob correlation. Something strange is happening with fratio.

Added some C tests for sat and solve_ph routines.
Added parameter 'source' to fprops_fluid, to allow data with a particular source to be specified (optionally). This allows forced testing explicitly of the RPP data even when Helmholtz data is also available.
Tweaked some convergence parameters in sat.c and solve_ph.c to get convergence across broader range of parameters for more fluids (more testing required).

Working on updating rankine_fprops and associated models to work with new fprops2 code.
Some issue discovered with (p,h) for water (added python/solve_ph1.py to check it).
Next cunit tests to drive some ASCEND models embedding FPROPS (note use of slvreq for this).

Merged (copied) fprops2 branch to trunk. This copy overwrites the trunk version of fprops,
and history is preserved via the fprops2 sequence. I hope that's OK...
