This is a basic example of how to create, plot, and analyze Phase Diagrams using the pymatgen
codebase and Materials Project database. To run this example, you should:

* have pymatgen (www.pymatgen.org) installed along with matplotlib
* obtain a Materials Project API key (https://www.materialsproject.org/open)
* paste that API key in the MAPI_KEY variable below, e.g. MAPI_KEY = "foobar1234"

This is a basic example of how to check a new material for stability using the pymatgen
codebase and Materials Project database. It assumes that you have already calculated
the energy of your predicted compound with DFT.

It is very important to note that this code does NOT do a detailed check to make sure
your computed energies are compatible with those in the Materials Project database
(i.e., uses the same functional, +U corrections, k-point mesh, etc). You must ensure
that the energies you provide are directly comparable with those in Materials Project,
otherwise this code will give you false results!

(e.g., MaterialsProjectCompatibility) in order to improve the accuracy of reaction energies
and phase diagrams.
