try turtle

[philbarker]

yaml + metadata is fiddly; try allowing turtle. Treat turtle and yaml metadata equally. Storing metadata from Turtle as rdflib.Graph makes sense; getting it into a python object (as metadata from YAML is stored in md.meta) is circuitous, but does suggest an extension of how metadata is stored

• [x] parse embeded turtle with rdflib & serialize into html
• [x] allow JSON-LD context to be set (having a context means you get compact JSON-LD)
• [ ] allow Turtle context (@base, @vocab, @prefix) to be set
• [x] store parsed graph in md object as md.graphs
• [x] store json-ld serialization of graph in md object as md.jsonld
• [x] store python dict representation json-ld in md.meta
• [x] store json-ld serialzn of YAML metadata in as md.jsonld
• [x] parse json-ld from YAML with rdflib & store in md.graphs
• [x] sensible tests to compare md.graphs

I'll be honest, the tests are a bit of a mess. Probably need a separate issue
