Breadcrum format suggestion

- Hey Jordan, I might be way off here so let me know if I am.
  I was thinking the breadcrum would show only the names of the
  pages, not the names of the group or anything, since each of those
  links has to be able to bring the user back somewhere.
  The last link (ABC Group) doesn't really tell the user they're in
  the Test Suite (or that they could go to it by clicking that),
  hence I figured that sort of info (Student/group name)
  could go in the top bar.

- This is just a testing branch so if you don't like the changes we can
  just delete it without consequence.

- Also, in the prototype there are no Groups, so we don't have to worry
  about that. The Matrix will only show a list of students.
Added Architecture Diagram to Design Doc

- It feels incomplete to me somehow.
  Did I miss some subsystems?
- Subsystem descriptions still to come.
