Added assumptions.py which contains functions used to help identify and/or remove duplicates or overlaps from input datasets

Updated line density tool so that output table meets some basic requirements:
-each input zone results in output entry
-no extra entries
-no lines in a zone is now a value of "0" instead of an implicit null like before
-ZoneAreaHa is not included in output, is duplicate information

TODO: if there is truly no data for a zone, no way to identify this yet
