Structuring of Media properties

[avinashresearch1]

• Big dictionary of pure component models (H2O, CO, CO2, etc.) from Clapeyron/data banks. Choose from pure component list.
• Generate mixture models from component models (use Claypeyron). Get out mixture property. (e.g. NaturalGasMixture)

Rough syntax

@named input_stream = MaterialStream(Medium = NaturalGasMixture)
@named out_stream = MaterialStream(AbstractMedium) # output has same pure components 
@named gibbs_reactor = GibbsReactor(; feed = input_stream, product = out_stream)
