concat no longer works on a generator

[jseabold]

I updated pandas and now my data loading scripts are broken.

Something like this works on 0.11.0

pandas.concat(pandas.DataFrame(np.random.rand(5,5)) for _ in range(3)).reset_index()

Does not work on recent master (6cd4adc).

changed in #3559

I guess this should be list_like (which would include generators.....)

[jreback]

the problem was that people did this:

pandas.concat(df1,df2)

and the first argument was restricted to a tuple/list/dict

@jseabold master updated...should be good to go now
