Added database insight component.

This MR adds a database component and overhauls the project readme.

Counsel AI has the ability to interact with an external database containing patient or client health records. Presented here is a sample program that outlines how the Counsel AI could ingest data from the database and use it to generate knowledge.

It does this by retrieving a patient's information and metrics, and uses that to generate a list of focus points for Counsel AI and the counselor to pay special attention.
