A resizable layout and a constructor that takes a CourseAssignment object
Merge pull request #23 from RichardHayesMassbay/master

A resizeable layout and a new constructor.
CourseReader update (not tested yet!)
- main issue will be making sure I counted the number of tabs correctly when I tokenized.
- any variables from Course class that are not in the Course Schedule file I set to null or zero. I'm assuming there is another class that updates them later.
Added partial functionality to the assignButton and adjusted the layout a bit.
