Added additional checks for hulls that may be coplanar, or otherwise problemmatic, and some other minor improvements

Fully implemented plotting with filtering. The results are okay, but nowhere near as nice as the built-in plots. Also, the compositions appearing on the x-axis corresponding to the phase boundaries seem to be shifted by a constant factor from the reference - need to look at this further

Working prototype of binary phase diagram plotting tool. Have NOT tested it for 4 dimensional plane yet, just trying to recreate phase diagram of LiCl-PuCl3

Added a function to pseudoBinaryDiagram class that gets all of the phase regions and all of the temperature composition points associated with a given phase region. Also added supporting functionality to thermoOut class.

Added utility function for converting from element fractions to endmember fractions for a pseudo binary system. This code can probably be simplified significantly

Added ability to skip states which are missing data. Still not sure how these states arise - perhaps there's something incorrect with the calculation parameters. Also added annoying python .pyc binaries to the gitignore

Removed normalization, it is more convenient to do this on the caller side so that the proper mass labels can be created first

Added a phase inclusion tolerance, i.e. for  below this tolerance, the phase fraction will be set to zero. The value was set to be the same as that in pseudoBinaryPhaseDiagramFunctions.py

Must specify fuzzy stochiometry when generating input script, not when running it, as there is no such argument
