[Talk-us-massachusetts] MassGIS address import -- on duplicates and weird housenumbers

[Greg Troxel]

If we think the massgis data is wrong, it would be good to find some
actual examples and check them, and talk to the town's GIS dept or
massgis about it.  One of the import rules is that we only import
correct data.  Of course, a large import will have some fuzz, but we
should understand how much there is.
