Adding Overlays<br />
Overlays are shapes that can be added to the map, there are different kinds of overlays, and each<br />
ovelay can be configured in stroke and fill color and opacity. The MapView exposes an overlay<br />
collection and a couple of functions that can be used to add an overlay to the map. Currently, a<br />
circle, polygon and polyline can be added to the MapView. Below is a sample of a circle and a<br />
polyline that is added to the MapView. Note that the code is wrapped with a BeginUpdate and<br />
EndUpdate. This is crucial to make sure the overlay shape has the correct position, and appearance<br />
when added.<br />
