BUG: dmpFlagger.initFlags sets all 'NIL' flags

The docstring of flagger.initFlags states, that when additionally to the data a dios with flags is passed, the flagger gets initialised with the flags set. But this doesnt seem to work.

with a dmp-flaggerobject flagger, and the following code:

testdata=dios.DictOfSeries(pd.Series(data=0))
flags=dios.DictOfSeries(pd.Series(data='BAD').astype(flagger.dtype))
flagger=flagger.initFlags(data=testdata, flags=flags)

i get:

flagger._flags:

     0 | 
====== | 
0  NIL |
