Made the EventListController use domain and range types, rather
than severity, domain, and event message. This allows it to be
more generalized, which should be helpful with different data
formats later on. #18.
The scroll position now moves down when a new row is added
to the data table. This means that when the scroll position
is at the bottom, it will stay there, even with new updates
adding onto the botton. #18.
Changed scrollDirection to ascendingScroll, which acts like
a boolean. Now there is proper communication between the
html and the directive itself. #18.
Created an mct-data-table directive. We are able to detect changes in
the height of the table now, which will be used to determine
any corresponding scrolling. #18.
When viewing an event message generator new messages are now added to the
bottom of the display, rather than being added to the top and pushing
the other messages down by one. #18.
