                                  PythonElementClassLookup

Element class lookup based on a subclass method.

To use it, inherit from this class and override the lookup method to lookup the element class for a node:

   lookup(self, document, node_proxy)

The first argument is the opaque document instance that contains the Element. The second arguments is a lightweight Element proxy implementation that is only valid during the lookup. Do not try to keep a reference to it. Once the lookup is done, the proxy will be invalid.

If you return None from this method, the fallback will be called.
