Overflow text on the search item labels is now hidden, with ellipses. New problem: Text is on a different line than the icon.
Added classes to the HTML so that CSS and Sass could get access to style the searchbar items. The structure for styling is now mostly set up.
Starting to modify the front-end so that the searchbar appears in the tree view area. Made the tree holder have relative position so that the searchbar is visibile for now. (Later will be different.)
