Publication page, addition of tags- Feature Request

[abhigenie92]

It would be great if there tags for the publications to make it easier for someone to view. For example: as on this page http://ai.stanford.edu/users/koller/papers.cgi

Also, if possible the abstract section could be dynamic. That is, be minimized by default and open up on clicking.

I like this feature👍 . Unfortuantly I don't have much time on this project at the moment. If you feel like you can code it nicely, make a pull-request and i'll be happy to merge it in.
