Diff to previous 2307
Merging in refactor of the C++ code, which is moved out of 'pygtk' and into 'ascxx'.
Adding support for IPOPT 3.9.1, the current latest version.
Support in dtar for parallel builds (possibly needs some testing still).

Diff to previous 2305
Minor changes to FPROPS cycle models.
Fix 'scons install' to also install FPROPS in Python path in Linux (still need to test install with Windows).

Rename 'node' to 'air_node' and 'stream' to 'air_stream' in brayton.a4c.
More plotting routines in cycle_plot.
Finalised combined cycle models including ammonia.
Small bug in nitrogen.c when testing (./test.py nitrogen).

Add plotting of p=constant lines on Ts diagram for the power cycles.
Add calculation of heat exchanger effectiveness (faulty!), trying to trap physically impossible heat exchange cases.

Added routine to calculate ideal->m and ideal->c for desired reference state values.
Adjusted toluene reference state so that s=0, h=0 for liquid at the triple pt.

Working on combined cycle simulation using toluene in the bottoming cycle.
Seem to be getting negative values of h and s for toluene in some cases.
