* This a an abstract implementation of interface iface_import_record
* An record is e.g. a single address or or single event.
* No mater where the records come from, at the end the get_record method comes out
* @todo whipe out the bool returns and use exeptions instead!!!
* @todo do we realy need the stepping? otherwise we also could deal with stream resources.
* The advantage of resources is, that we don't need to struggle whth stream options!
* @todo just checked out iterators, but not shure if we can use it.
* they iterate over public functions and not over datastructures :-(
