FlutterEarthGlobeController class

This class is the controller of the RotatingGlobe widget.

It is used to add/remove/update points and connections. It is also used to control the rotation of the globe. It is also used to load the surface and background images. It is also used to set the style of the sphere. It is also used to listen to the events of the globe.
