thx thomas (you seem to answer all "a&p" questions of the world)
so you mean i have to provide an implementation (rather then an extension)
of "PlaceHistoryMapper"? will @WithTokenizers work on that? Or do i have to
implement all stuff for all places? or to make it simple (at least for me
;-)) could you probably give me a draft of "
PlaceHistoryMapperWithFactory".
