Ingest additional treebanks

[jacobwegner]

• Bring in data from treebanks (Perseus compliant Treebank data + Proiel)
• Gorman trees
• Creating a readable "version" from the treebank data
• Integrate https://github.com/bellahwang/treebankstats
• https://github.com/gregorycrane/glaux-trees/tree/master/public/xml (via https://github.com/scaife-viewer/beyond-translation-site/issues/95)
• Attributions

As noted on our call yesterday, we would prefer to to "infer" text part structure on top of the syntax trees, i.e.

http://beyond-translation.perseus.org/reader/urn:cts:greekLit:tlg0012.tlg001.perseus-grc2:1.1-1.7?mode=syntax-trees

This will require rethinking how we ingest syntax trees a bit. I have a few things in progress on scaife-viewer/beyond-translation-site at feature/glaux-trees:

@gregorycrane Still working through the other trees, but I've added the citation scheme formatting:

@gregorycrane The Anabasis trees are now visible on the dev instance:
