The GetSpecies command returns a list containing the chemical names known to the ThermophysicalData:-Chemicals package.

These can be used with the ThermophysicalData:-Chemicals:-Property command to get thermodynamic data.

If the speciesnames=original option is provided, then the original names, as defined in the data source McBride et al. 20002, are returned instead of the default names.
