/** Developers can import RMInteractiveSource in order to enable embedded interactivity in their RMMapView, RMMBTilesSource, and RMMapboxSource objects. Interactivity is based on the UTFGrid specification, which is a space-efficient way to encode many arbitrary values for pixel coordinates at every zoom level, allowing later retrieval based on user events on those coordinates. For example, the user touching a pixel in Spain could trigger retrieval of Spain's flag image for display.
