[MapQuery] Code sprint

[Volker Mische]

Hi all,

the code sprint is mainly about merging the EduGIS with my code. But in
case you (yes, I mean you all! :) have still some code around that might
make sense to use as a basis or inspiration, please make sure to upload
it somewhere and post a link.

I expect from the code sprint that we finally end up with a usable API
we will stick to, hence all input is welcome :)

Cheers,
  Volker
