Imports csv items into mongo

Environment variables can be injected in 2 ways.

1. A config file.
2. The system environment variables.

When using the config file, create a config file application.conf located under
src/main/resources

mongo_address=
mongo_port=
mongo_db_name=

mongo_auth_uname=
mongo_auth_pw=

When the user gets prompted for their input to the path, the raw path to the files should be
entered. eg: c:/users/username/desktop/csvFiles
The files under this directory should be .csv
