Coordinators Who are Also Helpers

When you create a new coordinator, they are given a separate username and password to sign in as a coordinator.

Any coordinator who also helps for shifts will also need to be added as a helper so that they can be assigned shifts. They will then have two separate sign ins:

1. One username and password to sign in as a helper (if they want to propose trades to other helpers, etc.) 
2. A second username and password to sign in and perform their permitted coordinator functions
