FOR REVIEW:
-updated the user list page to include research interests
-beginning to implement a "view user profile" page so users can see the contact information and portfolios of other users. Currently the page retrieves only the current user.
-Added a "private profile" boolean field to user model so that users may hide their information from other users.
Merge branch 'Richard' of github.com:YfLn/CEN3031FA14 into Richard
