Hackathon justin

This is pull request for work started on Hackathon, mainly improving Model class with new coding convention of ModelComponent (e.g. replacing the old property style with the new property style). This also deals with a bunch of issues: #95, #99, #100, #101, #102.
Just a note; we'll need to ensure some consistency across Components about how we name Output's. Do the outputs for Body follow the same syntax?
