Implement comparison groups

Comparison values must be stored in an extra model (per grade and subject) and should not have a link to the student or group, but a hash of the teacher's ID.

Comparison values should only displayed if there are at least three different teachers and five different results.

Test scenario as fixture with fresh database

  1. Teacher Jane Doe
  • Group: 8c:Mu
  • Group: 5c:Mu
  1. Teacher Aunt Dawn
  • Group: 6c:Mu
  • Group: 5a:De
  1. Teacher Mad Wilson
  • Group: 7a:Mu
  1. Teacher Lara God
  • Group: 6a:Mu
  • Group 9d:Mu
  • Group 6a:De

Each group just gets three students:

  1. Student A: Part A best, Part B worst
  2. Student B: Part A worst, Part B best
  3. Student C: Part A best, Part B best

Two comparison groups: 5 to 6, 7 to 9

Each person needs a user, students and teachers get one group.
