Updated logic for calculating right endmember fractions from the endmember compositions and a given element composition. Previous logic assumed the existence of an element that was in one endmember and not the other to calculate the endmember fraction, but this is not the case in general. Also added preliminary function for computing melting and boiling points

Updated .gitignore to include pytest files, and updated table of contents generating logic to ignore directories listed in the .gitignore

Actually added outputs directories to the git repo. Due to the way git tracks files, these directories are only tracked if they contain files, so they now contain .gitignore files so that they're tracked.

Added script to test that all .py scripts in the saltOptimization directory run, and updated ci workflow

A workflow for cloning the dependent repositories and running the tests using pytest.

Removed extraneous symlinks to thermochimia directories, and updated paths in the benchmark and calculation scripts

Need to resolve thermochimica_output path first otherwise the logic that's meant to generate the relative path to the desired output directory will fail
