Jan-Philipp Litza 6fc1423124 Make handling of node attributes more flexible.
This commit makes Nodes special dicts that return None-like objects for
inexistent keys, making it a dynamic attribute store.

Also, it removes the D3MapBuilder and moves its logic to the Node and
Link classes' newly introduced export() method. Only they need to be
changed to populate the final nodes.json with more attributes.
