#154 closed enhancement (fixed)

chopping routines for tables with large geometries

Description

Mapping or querying / analyzing tables with large (many vertices) features can be very inefficient. Some strategic de-normalization, in the form of chopping big things into smaller things, can improve performance greatly. Chop polygons into little squares, and associated boundary table of lines. Chop lines into shorter lines.

Changing version to 2.0 so it doesn't appear as a blocker against a 1.4 release.
