/**
* The JXMapKit is a pair of JXMapViewers preconfigured to be easy to use
* with common features built in. This includes zoom buttons, a zoom slider,
* and a mini-map in the lower right corner showing an overview of the map.
* Each feature can be turned off using an appropriate
* isXvisible property. For example, to turn
* off the minimap call
*
*
* jxMapKit.setMiniMapVisible(false);
*
*
* The JXMapViewer is preconfigured to connect to maps.swinglabs.org which
* serves up global satellite imagery from NASA's
* Blue
* Marble NG image collection.
