[rastersize]

:warning: Not yet ready to merge :warning:

See pivotal story 48741037 “As a user I want to get suggestions for which tags I can search for while searching.”

Todo

• [x] Create view which renders a tag as a discrete “token” (no can’t use GCTagList for one of the places :(). It should also be extensible enough such that it can be used for a user.
• [ ] Create subclass of UISearchBar which renders tags using the “tag token view” Will have to happen later, really crazy task.
• [x] Add container view for the tag auto completion stuff as well as the insert new tag/user buttons.
• [x] Add insert new tag button.
• [x] Search and use real data.

This could most likely be merged into master for the acceptance test.
