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.
