Main README example TRAPI Query needs updating

[RichardBruskiewich]

Just a placeholder issue pointing out the fact that the main repository README needs updating to TRAPI 1.4. This may just mean transferring some of the examples from the implementation guidelines into the root README.

For example, extending the entire example to be closer to 1.4 spec (i.e. with addition (i.e. "auxiliary_graphs") and restructuring (results.edge_bindings moved into "analyses").

Roughed in (not totally right for sure...):
