This pr resolves #810 and shows how to use a stop with a SymbolLayer to give the effect of an icon switching based on a particular zoom level.

@LukasPaczos has confirmed my suspicion that iconImageId can be used with expressions/zoomLevel , rather than using setMaxZoom() and setMinZoom(), as I do in this example.

I will refactor this example to use expressions and iconImageId correctly.

For reference during expression refactor: https://github.com/mapbox/mapbox-gl-native/blob/master/platform/android/MapboxGLAndroidSDKTestApp/src/main/java/com/mapbox/mapboxsdk/testapp/activity/style/ZoomFunctionSymbolLayerActivity.java#L123-L126

Ok, just pushed a commit to refactor this example so that it uses the Expression.step() expression.
