setup database and add enroll_data function to insert data.

 currently takes the raw api dictionary and only inserts the first data point.
generalize enroll_data() to properly handle lists with more than one item.
modify enroll_data() and add function format_data().

Format data probobly will not be useful in production, but allows me a way to validate data taken out of db.
add crude unittest suite.
add file .gitignore and configure to ignore .swp files from vim and .pyc files.
