PropertyChangeListener, EventListener, Manager

public class TransitManager
extends AbstractManager
implements PropertyChangeListener

Implementation of a Transit Manager

This doesn't need an interface, since Transits are globaly implemented, instead of being system-specific.

Note that Transit system names must begin with IZ, and be followed by a string, usually, but not always, a number. All alphabetic characters in a Transit system name must be upper case. This is enforced when a Transit is created.
