renamed rebuild to ingest because that makes more sense
Added a google maps example
Added a python native address lookup module
cleaned up the interface for address parsing
Pulled the digest invocations into their own module. This may be better folded into ingestion, but the basic idea is that these are operations that operate on base data that has been ingested.
Also cleaned up the address resolution, so that it now returns unit numbers and fails to return when we don't have the blocklot for the address.
Patching the tolerance of 12-A MAIN ST type addresses
Added a simple service to resolve addresses
Added an extraction for frenquency of property transfer
