Component

Grade processing

Summary

Implement a variant for #111 that works for non-individual courses, allowing non-standard EC for all courses to be registered.

This is tricky because the grades have to be booked in an entirely different way (directly on the Y-class with EC rather than on the T-class as usual). Keeping in mind also that both registration and grade status are going to change with the implementation of GLASS, we might not want to hurry too much with this.

Question: why don't we process all grades at the Y-class level?

[goomens]

We are going to process all grades at the Y-class level and once that is the case, this will be easy to implement.
