class SocrataPager(Socrata):
def get(self, dataset, *args, limit=None, offset=0, where=None, order=None, page_size=None, **kwargs):

which is passed as the limit kwarg to Socrata.get. limit is the total number of records to
return, across all pages. Note that the method is a generator.

while not done:
results = super().get(dataset, *args, limit=page_size, offset=offset, where=where, order=order, **kwargs)

yield item
offset += len(results)
done = (len(results) == 0) or (limit and offset >= limit)
