Retrieval for all objects:

For the implementation of "getObj()" we need the information whether an
object has been refined or not. If we are on level n and an object has been
refined on level i<n, we have to skip this object. Since we have a consecutive
enumberation of objects, we have a simple mapping from the parent id of the
object to
