The Physics Derivation Graph is for workflow management

There's no complicated math underlying the Physics Derivation Graph. The code base is primarily about tracking numeric indices and strings in Python dictionaries and lists read from plain text CSVs.
Similarly, there are no fancy algorithms in the software.
The lack of complicated math and fancy algorithms is because the Physics Derivation Graph is for workflow management of mathematical Physics. Encoding the logic and processes is merely management of simple data (numerical indices, strings to represent math).
