Documentation

[wkiri]

• Add README to src/
  • Steven: describe how to parse a document (full details on wiki page)
  • Kiri: describe how to create SQLite database (ingest, review with json2brat, update)
• Describe how to deliver PDS bundle - this has many steps and probably should be a wiki page instead; will be copied from github-fn wiki page
• Update wiki to remove mentions of Solr and replace with SQLite

I've updated the instructions in the README to include how to go from the JSON file to an SQlite database:
https://github.com/wkiri/MTE/blob/master/src/README.md

I also removed mentions of Solr here (SQLite instead):

@stevenlujpl Could you update the parser instructions here to include the option of applying unary relation extraction?
