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).

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...

Add fprops_Tvsh_ph to asc_helmholtz for calculation in terms of (p,h). The
routine does not seem to work particularly well though.

Seem to have fixed the solve_ph problems, but new problems in fprops_sat_p have arisen.

Avoid stepping outside saturation region in fprops_sat_hf.

Improved first guess has eliminated many of the errors, still problems though.

The (p,h) function is converging almost everywhere. The home-made Newton iteration wasn't starting well for supercritical states
when the starting guess had rho = rho_c, so changing slightly away from fixed almost all the problems.
