Issue92

This is a solution for target objects that do have list properties with getters, but no setters. Its assumed that the getter is initialized and returns an empty array the first time.

If a target object has no setter, and the property it concerns is a list, the respective getter is treated just like a setter.

Wrt. to Type, I am wondering whether we should keep on adding booleans to the constructor. I did so, currently, following the approach which is already there.
