Error in the index attribute

[nalsabhan]

First of all, thanks for this package. Moving back and forth from python to R is frustrating. I have an issue. My index is RangeIndex(start=0, stop=152, step=1) and pre_period = [0,109]; post_period = [111,151]. I have 2 columns in pandas and when I pass it to CausalImpact I get the following error:

hey you might try to Change the line if isinstance(data.index, pd.tseries.index.DatetimeIndex): to if isinstance(data.index, pd.core.indexes.datetimes.DatetimeIndex):

this is probably caused by a too new Pandas Version you use where they changed some stuff with the index

ah well spotted, that seems to have fixed it now, i had moved to pandas 0.20 but was running tests against 0.19 so they didn't pick this up
