Divided mercury_model.py with a separate file mercury_minerals.py with the material parameters
Updated mantle minerals and put placeholders for core minerals
fixed opx fe number
Added some mineral parameters from Hauck 2013 and contained references, but not sure how to handle T-dependencd of EOS
Now have a working model with core parameters, but some of the parameters (liquid FeS) break the build_planet.py function.
Added adiabatic profile to build_planet.py
Merge pull request #3 from cider-team-mercury/adiabatic_profile

Added adiabatic profile calculation to build_planet.py
