MergeSourceBuildingVisitor helps to build the "hull" of a collection of {@link OsmPrimitive}s which shall be merged into another layer. The "hull" is slightly bigger than the original collection. It includes, for instance the nodes of a way in the original collection even though these nodes might not be present explicitly in the original collection. The "hull" also includes incomplete {@link OsmPrimitive}s which are referred to by relations in the original collection. And it turns {@link OsmPrimitive} referred to by {@link Relation}s in the original collection into incomplete {@link OsmPrimitive}s in the "hull", if they are not themselves present in the original collection.
