House keeping...
edited the README
Modified setup.py, built Sphinx and Apidoc again. Pruned unwanted entries from REQUIREMENTS.txt. Au now depends only on Django, PyYAML. If PostgreSQL DB is required, psycopg2 is needed. For sqlite3 usage that can be deleted from REQUIREMENTS.txt. Apidoc/ Documentation uses Sphinx. There is no other Dependency.
Added Search for Drugbank as well. Now users can search either FDA / Drug bank reference
