Interface: Navigation

Navigation is an interface that provides some methods used to control the camera.

	AstroNavigation	Provides a camera located at the center of the scene. The camera is inside the globe. It is used to view the sky
	PlanetNavigation	Provides a camera, located outside the globe and looking at the globe. It is used to view a planet
	FlatNavigation	Provides a camera to navigate on a 2D map - Only available in a Planet context
