* Allow fluids to be used with SRK in multi-fluid model that have a dash in name
* Add ability to use SRK and PengRobinson as one-fluid transformations in multi-fluid models;see #1346
* Changed API for AbstractCubic so T_r and rho_r are settable
* Also add the ability to set to Peng-Robinson; see #1346
* Actually set the cubic EOS in multi-fluid model
* Enable both SRK and PR for cubic transformations in multi-fluid model
* Add parser for HMX.BNC from REFPROP; closes#1294
Also move configuration variables into main pybind11 module
* Add the ability to over-write departure functions and binary interaction parameters
* Added first working version of VTPR;
* Get VTPR building hopefully
* Remove more constant iterators
* Make VTPR accessible through factory
* One last const iterator
* Fix a_alpha bug and make sqrt(2) into sqrt(2.0)
* Added analytic first derivative for VTPR
* Fix another set of sqrt(2) -> sqrt(2.0)
* Add some info on the derivatives for VTPR
Looks less hopeless than I had feared
* gE/RT needs to be multiplied by RT; closes#1161

* Add VTPR code from @JonWel (#1194)
* 1rst draft to implement a simple volume translation to cubics
* A bit more of VT
* Derivatives for volume translation
* Better cm initialisation
* Solves the cubic equation with volume translation
* Correct the volume translation analytic development
Looks good now
* Update VTPR to be able to use volume translation
* Unprotect cm_term
This allows it to be used from the VTPR backend
* Update CoolPropLib.def
* Better derrivative of PI_12
The expression is simpler this way
* Solves #1176
Thanks @ibell
* Change the way the volume translation parrameter is set
* Start the bm derivatives for VTPR
* Correct one derivative
* Small bug
* Better bm derivatives for VTPR
* Add am and bm component derivatives for VTPR
@ibell I did not check yet the component derivatives of this commit, bu I checked the other ones with your code.
I'll have to addapt your code to also check these ones.
I separate the `am_term` and `bm_term` as the `am_bm_term` function was called twice. This reduce the call to the am_term part as this part ends up being called only once, and this helped writing the component derivatives.
The tau derivative is done numerically untill we find time to develop the analytical one.
The `am_bm_term` function started with a `set_temperature()`. I did not checked yet why this is needed and put this set temperature at the beginning of each of the `am_term` component derivatives.
I'll try to addapt the checking code tomorow.
* tab to spaces
* Re-writing of cubic coefficients
Introducing 3 intermediary varriables that simplify the cubic's coefficient with the volume translation.
