title: Write Data to go_maps_ext in typo3
body: <p>my problem is the following: <br>
  I have multiple websites in typo3 an want to add the go_maps_ext to all of them. It would be very much work to type the address and coordinates manualy to all of them, so i wrote a extension which gets the data out of an database. My problem now is that I don't know how to pass the values I got to my extension. i need to create a new go_maps_ext-Map and pass the values address, latitude and longitude to it. Can somebody help me?</p>
