Add unit tests and requirements for geopandas factory.

Geopandas factory now can receive a geojson file or a pandas data frame by using the optional variable data_frame in the constructor to be consistent with the rest of the factories

So from:
 ConstructionFactory('gpandas', dataframe)
to:
 ConstructionFactory('gpandas, '', dataframe)
