Adding django helper files as well as solr setup helping files

[horriblyUnpythonic]

This is work done for a project done at Georgia Tech in collaboration
with the FDA.

If you'd like any of this code moved, just let me know.

There are two main contributions
First is some legwork done for a django project that maps to the database setup by the code in bulidmimic. This consists of the premade settings file and the file etc/django_info/README.md that oulines what was changed from the default. It also contains a models.py file that has been edited to more closely match the foreign key relations set up in the postgres db.

Second is some work for a solr instance config as well as a small python interface to query it. This allows for fast retrieval of documents in the note events table.
