An Access Point is any one, or a set of, doors, ramps, gates, entrances or
exits that behave as a single entity.
An Access Point can be one physical door, but in the case of a vestibule
or a mantrap, it can be two doors that are controlled together.
Through Access Points one can manage access across the system
and exercise control over physical doors.
