Calculate the Compressibility Factor 'z' for Hydrocarbon Gases

Computational algorithms to solve equations and find the compressibility factor `z` of hydrocarbon gases. Correlations available: Hall-Yarborough, Dranchuk-AbuKassem, Dranchuk-Purvis-Robinson, Beggs-Brill, Shell and an Artificial Neural Network correlation (Ann10) by Kamyab et al. The package uses the original Standing-Katz chart for statistical comparison and plotting. Applicable to sweet hyddrocarbon gases for now.
