			Peng robinson and helmholtz in agreement on pressures now. If I can just get the helmholtz energy departure function working then it'll be working in time for the deadline.

			Difficult week, main computer broken, difficulties compiling on second. Finally succeeded in running scons. Work on python bindings, they're working now but need tidying up.

			Thought for the day: SWIG is ''really'' clever.

			Peng-Robinson EOS now successfully calculates <math>p(V,T)</math>, <math>V(p,T)</math> and <math>\Delta h(V,T)</math>, <math>\Delta s(V,T)</math>. Redlich-Kwong EOS also works, but has additional '''untested''' support for a,u,g departure functions. Once the two new EOSs are integrated with current ideal and saturation calculations then we'll have two new EOSs.
