This example creates a map that starts in Auckland, New Zealand. The map is
restricted to New Zealand. The user can pan away from Auckland and explore other
New Zealand cities, but the user cannot pan or zoom to beyond the constraints
set on the map.
Try panning north, or zooming out, to see what happens when a user tries to move
beyond these boundaries.
