Study Plan Validator - Githubissues

Create a validator for study plans to check if courses met their prerequisites (i.e. courses in study plans have their prerequisites met and before them in the plan)

Find a way to parse / evaluate NUSMod's prerequisiteRule:
Ideally what it should look like is something similar to the list of dicts below

"CS2030S"
prerequisite = "if undertaking an Undergraduate Degree then ( must have completed 1 of CS1010/CS1010E/CS1010J/CS1010S/CS1010X/CS1101S at a grade of at least D)"
prerequisiteRule = "PROGRAM_TYPES IF_IN Undergraduate Degree THEN ((COURSES (1) CS2020:D, CS1020:D, CS1020E:D) OR (COURSES (1) CS2030S:D, CS2030:D AND COURSES (1) CS2040S:D, CS2040:D, CS2040C:D))"
