* SO: The overlay class is quite convenient.
* But managing the information creation solely inside this
* class restricts us massively.
*
* Maybe a restructuring would be good, that we can handle
* the creation of information with a callback and can adapt
* to any occuring situation.
*
* e.g.
*
* overlay.informationHandler((geo, type, item)=>{
* switch(type){
* case "popup":
* createPopup(item.information)
* break;
*
* ....
* }
* })
