07cc87b8b2 A partial resolution of https://github.com/CoolProp/CoolProp/issues/107 
All internal values are molar, so the error message is only truly useful if you are using molar units

0dcdf7ef5d Implemented PQ for pseudo-pure to close https://github.com/CoolProp/CoolProp/issues/92 
* As a consequence, made update function take CoolProp::input_pairs enum as first input (thanks @jowr for the idea)
* Decoupled the pre_update and post_update functions in order to allow for more creative update functions using guess values, etc.
