Description

There are some elements of the graph api which would be useful from the graph-traversal api.
One such method is graph.features().
This is something that a client should use frequently if they want to write portable code.
see https://tinkerpop.apache.org/docs/current/reference/#_features for current usage.
The new api would be g.features(). 
The result would be serialized as a map of maps of boolean values.
