+. Removing the "implements Constants" as it is a bad pattern. Interfaces
+  should represent types. It also makes the UML diagrams very hard
+  to follow. We're just going to use the fully qualified GraphConstants.{x}
+  idiom.
+
+. Added the Graphable interface to allow any arbitrary object to be
+  manipulated like a vertex in a graph.
+
+. Added a util package that has a dependency resolver that uses a depth first
+  search to sort the dependencies for a set of objects that implement
+  the Graphable interface. The resolver also works with Strings and
+  lists and deps stated as lists of strings so I can resuse the test
+  I wrote for the DependencyEngine in jjar.
