+ * Kept very minimalistic because all options would require much reiterating which we don't want.
+ * This class is multithreading! Don't expect it to contain the right data after an
+ * addRegionsToBinAsync call, but await it's completed() signal. Also beware! This function
+ * _does_ clear() before addRegionsToBinAsync! (hence not conforming to the regular semantics
+ * of HistogramProducers if you'd take addRegionsToBinAsync = addRegionToBin, but since that is
+ * already violated with the asynchronousity of it that is not really an issue anymore, I think)
