Returns an array (or CSV string) of major_codes from the student_degrees table for this student.

If bool_check_for_allow_dynaic is TRUE, it means that, if the student has more than one degree returned, we will make sure that they all have allow_dynamic = TRUE. If they do not, we will use the first is_editable degree we find ONLY. We do this because that means the student had a situation like we see in FlightPath 4x, where only one degree may be selected at a time, and the is_editiable degree is the track/option they selected.
