This completes the transitions started in Ic5a61365ef0132476b11bdbf1dd96885e91c3cb6 The new file plugin.py is the place to start with this change. The abstract base classes PluginBase and NodeBase are heavily documented. NodeBase essentially replaces Digraph.Node The changes in level?/*.py make no functional changes, but are just refactoring to implement the plugin and node classes consistently. Additionally we have added asserts during parsing & generation to ensure plugins are implemented PluginBase, and get_nodes() is always returning NodeBase objects for the graph.
