DimensionHierarchy

Finds which child resources belong to a particular parent resource.

This supports going multiple layers deep into the hierarchy. So for example if you have countries with locations with buildings with rooms, allows you to find all rooms in a particular country.

This does not support non-resource dimensions. We might still add support for this at a later stage, which is why the class is named DimensionHierarchy instead of ResourceHierarchy.
