Notes and known gaps

Covers states, counties, places, districts. CLASSFP, LSAD and FUNCSTAT are kept as census_classfp/_lsad/_funcstat, so incorporated places can be told from CDPs (Jurisdiction.place_class/1); existing places are backfilled by Release.backfill_place_classfp/0. Per-file import jobs are logged in tiger_imports.
