Accessors to children

Lukas, When PRChildren is empty, I am getting uneccessary database accesses at every leaf node. I am sure that there are several ways of solving this but for now I am experimenting in my image with... PRStructure>>#childrenDecoration removed and an access interface defined for children... #addChild: #childAt: #childAt:ifAbsent: #childAt:ifPresent: #childrenIncludes: #removeChild: Such that if there are no children then no PRChildren decoration is added into the structure's decorations. would this change be acceptable?
