VLE calculations using Antoine's Equation and Raoult's Law

These files demonstrate the calculation of a T-x-y diagram for ideal mixtures in equilibrium with an ideal vapor, whose vapor pressure follows the empirical correlation of Antoine's Equation.

We grab Antoine's coefficients from the NIST webbook using requests and BeautifulSoup. We also use numpy and matplotlib.

This is useful for illustrating extraction of data from structured web pages.
