crashes on multi-type node

[cbizon]

after going to answercoalescence, we can have nodes in the query_graph that look like:

{'id': 'extra_qn_0', 'type': ['named_thing', 'biological_entity', 'disease', 'disease_or_phenotypic_feature']}

But the viewer doesn't like that array of types, and won't work unless I replace it with a single type.

This should be fixed in version 0.2.0, which is TRAPI 1.0 compliant and can handle lists of categories.
