Sub period type

Sub period type is a fixed list of values that Chalk uses for sub period type. The allowed values are QUARTERLY, SEMESTER_BASED, TRIMESTER_BASED, NONE. A record can only ever hold one of these exact values, which keeps sub period type consistent across curriculum, assessment, faculty, scheduling, accreditation, and budget records, as well as the API. When you see one of these on a record, it is one of the defined sub period type states rather than free text, so reports and automations can rely on it.
