Geopandas join returns pandas DataFrame

[TaylorOshan]

For exmaple:

boros = gp.read_file("nybb.shp")
populations = pd.read_csv("populations.csv")
populations.set_index('BoroCode', inplace=True)

joined = boros.join(populations, on='BoroCode')
type(joined)

pandas.core.frame.DataFrame

Output should be:

geopandas.geodataframe.GeoDataFrame

population.csv data:

BoroCode,BoroName,Pop
2,Bronx,1385108
3,Brooklyn,2504700
1,Manhattan,1585873
4,Queens,2230722
5,Staten Island,468730

@TaylorOshan can you add a populations.csv file to the repo?

@sgillies I'm about to file a PR to pandas on this.

@jwass Great! Wish you were here.

@sgillies Me too. Definitely sad to miss the conference, the sprint and meeting everyone. But I'm really happy to see all the progress. Hopefully another time!

@jwass Meanwhile I have a workaround at 20010c5.
