issues were happening with author id being a uuid, so author now has an author_id field that is a UUID. ALso, took away displayName, user.username works now
error where the same uuid was being generated for each instance of Author fixed :) uuid.uuid4 should have been called instead of uuid.uuid4()
Merge branch 'rest_post' of https://github.com/awwong1/CMPUT410-Project into rest_post
fixed links to author profile pages in search results and friends.html, now uses author id rather than username to get to their profile
