Dios integration

@schaefed @luenensc

Dios is integrated, nearly all tests run again. So far i only implemented the Baseflagger interface. i merged develop into dios_integration, so that now the merge in the other direction should work without further problems.

We should do this soon, because new commits on develop need new adjustments afterwards (kick Dataframe for DictOfSeries..., fix use of df.index, and so on so on)

some test still dont run, but i find them much to complex/abstract to understand and fix them quick, ples check this.

cheerio B
