## TODO
## Set password parameters
## Add username attribute to User and authenticate with username instead of f_name.
## When User is done with an activity, they loop back to the options for their role (rather than looping back to the login)
## Logout option that loops back to authentication method
## Only staff Users have ability to close program.
