set up to dump to MongoDB instead of PostgreSQL

Remove __pycache__ directory

able to parse objects out of the job description, but extracting in mass w/ error handling is a little difficult. Most recent run is in parse_description_test notebook thats able to connect to psql and then extract a sample set of 74 descriptions.

updated config in readme

re organized the file structure in order to work with building a streamlit app to test the job description extraction.
