Module: lib/localauthentication

authenticate users with a username and password. Accept a memberID as a username, and case-sensitive lastName as a password. When authentication is sucessful, a user object is passed to the done function, which represents the logged in user. The object contains all known properties. There is an extremely rare edge cases where the behavior is undefined. If a user has the same last name and memberID as another member in a different council AND both of those members are in this database, only the first match will be returned. If this ever comes to be the case, a drop down box of councils should be added to the login screen and the council number can be added to the search query for disambiguation. OR even better, this login could be integrated with the BSA SSO system.
