show and hide a feature

This example loads a map of Africa using the "AFRICA" key.

The "AFRICA" map was created using the Mapzania MapStyler.

See www.mapzania.com/manual/concepts-mapstyler for more details on how to use the styler.

Also see www.mapzania.com/jsapi/map-object for more details on how to create a Mapzania.Map object.

The example uses the "usingLayer" method of the Mapzania Map object to make a chained call to the "usingFeature" method of the "COUNTRIES" layer.

For more on layers see: www.mapzania.com/manual/concepts-layers

For more on the Layer Object and the "usingFeature" method see: www.mapzania.com/jsapi/layer-object
