Created way for parents to be highlighted if all of their children are as well (when adding dependencies), however the animations are slightly delayed with the parents, so trying a new approach.
Completely fixed up the interface for adding prerequisite nodes. Have made it so that one primitive bar exists per page (not per tree as it was before), and am working on it becoming minimizeable.
