Viewabstract

Every abstract result now has a button to view the abstract in full. A modal pops up with title, author first & last name, and the abstract. The click calls a function in abstractlistgroupitem.js, which sets up a broadcast message through a service (abstractmodalservice.js). The MainCtrl has a listener for the broadcast. MainCtrl then updates the content that goes into the modal. The modal is in main.html.
