Rec mod deconstruction in progress
Rec Mod: Need to add synchronization
Added recommendation service, removed mod, changed directive.

The directive now is passed the whole url, this makes it far easier to use after a query to dynamo (it has the full link).

The directive was also changed to use ngshow to not show blank abstracts.
Added documentation. Fixed rec duplicate bug.
The duplicate bug was that the url's were different so it was possible for the same abstracts to have been displayed.

Viewabstract
Rec and abstract refactorings
Changed the names to better reflect that we are using links now.
I also removed the use of a hash since it didn't make any sense.
