Feature/generate

[gkellogg]

• Add Vocabulary.to_ttl, to_jsonld, and to_html to generate pretty version of Turtle, JSON-LD and HTML+RDFa for the vocabulary, using some heuristics on the values from the Vocabulary description.
• Generate triples from graph, rather than directly from vocabulary, and allow the graph to be provided as an optional argument. Also, allow additional prefixes to be added via optional argument. This allows the vocabulary definition to be used to get data that may be excluded from the built-in version, including literal language and datatypes.
• Add gen-vocab CLI command.
• HTML+RDFa can use either ERB or Haml templates (defaults to etc/template.erb). CLI help points to repository location containing templates, allowing customization.

Note, there are CLI changes on the develop branch or RDF.rb, which need to be released along with this as a version 2.0.1.

Awesome. I'll be able to give this a more serious look over the weekend.

The failing tests are rbx specific; they seem familiar from my rdf-ldp work, but I don't think I ever tracked down the source.

I thought I had avoided that problem here. I'll check again. It stems from a problem with RDF::Vocabulary::Term#to_uri that may relate to named argument handling in Rubinius.
