HelmholtzMedia Helium: transport properties not implemented

Helium does currently use transport properties of Butane! Instead, it should use the special helium correlations, but these are not yet implemented.

Comment by @casella: Dynamic viscosity in the Helium model doesn't work, looking at the implementation it seems that the "right" coefficients are missing from the table (only integer numbers show up in the code)

@casella Helium viscosity is now implemented, using the same special hardcoded algorithm as in RefProp. Results have been manualy tested (~20 points) to be identical, you are invited to do further testing. Thermal conductivity will come later.

Thank you Matthis!

We plan to use your model for a library on which we'll be going to publish extensively. Can you point me out the correct citations for your library?

You are welcome! Feel free to submit more issues if there is anything that could be improved. Also, if speed is an issue, I could try working on that. The github repository lists some publications that you could cite: https://github.com/thorade/HelmholtzMedia#library-description

The Modelica 2012 conference paper could be seen as the official publication,
the publication in Environmental Earth Sciences describes some details related to derivatives, index reduction and root finding,
and then finally my PhD thesis sums up the content from all other publications - it will be published as OpenAccess later this year.
