-LoggingIn.java : added a login page for manager. Still working on the setup of the login page though.
-LoginOutEven.java : added Manager data member, a LogInOutEvent for the manager class that is an overload to the user class's LogInOutEvent, and a getManager
-PROBLEM IN THE LogInOutButton.java : since adding the manager LogInOutEvent, the fireLogInOutEvent in the LogInOutButton.java has a problem because it has to deal with both constructors.  I wasn't really sure if we should just create a new fireLogInOutEvent (one for Manager and one for User), or if there is a better way of dealing with the LogInOut.
-(I did not change anything in the LogInOutButton.java or anywhere else.
