Possibly they are entirely working, but they are hard to debug because doing the numerical derivatives correctly is very tricky, especially shifting the mole fractions while keeping molar density constant. A new method might be needed for testing use only.

closes #33

Replace missing headers as needed

See #16

Had cast to wrong type

Not the problem, it was the pow(x,1/3), where x < 0

A test that nonpolar works with multipolar

Added multipolar terms; doesn't compile on mac anymore

Appears to be working, additional testing required. Generalizing to handle G&V and G&T correlation integrals remains

Very subtle problem with handling derivatives at zero density

Another bugfix release is needed

Closes #34

Closes #40

Can do binary mixture tracing now!

Seems to be working

Doesn't have the claimed critical temperature; closer before fixing the erroneous coefficient

Ready for Python!
