Use of NeqSim extended pure component database

[EvenSol]

NeqSim 3.0.49 comes with two pure component parameter databases: standard and extended. Standard database has properties of about 250 components while extended database has properties of more than 50.000 components. Use of standard database will be faster, as the table is loaded as an embedded database during calculations. The extended database contains all components available in the standard database with same parameters.

Standard: https://github.com/equinor/neqsim/blob/master/src/main/resources/data/COMP.csv
Extended: https://github.com/equinor/neqsim/blob/master/src/main/resources/data/COMP_EXT.csv
