Added Collector.RemoveLabelled()

sandersaares · sandersaares · commit 602c9a223555 · 2017-02-07T09:09:11.000+02:00
This allows removal of labelled child collectors when data with some set of labels is no longer desired to be exported.

Usage is the same as .Labels(), just in the opposite direction.
