Created DCREngine project structure. Also created basic, low-level DCR data models (Activity, Relation, Graph, etc.) and high-level DCR components (GraphCreator, GraphExecutor, GraphSaver, etc.). I have made basic required method skeletons for some classes (those of which we know that we have to make).
