Major changes:
Compiled code is now distributed in multiple files according to their
uses/purposes
Re-factored AoN with the following changes:
Network loading now is cascading. Presents worse performance for small number of
zones, but it is a good improvement for larger problems.
Creation of TranspoNets. Consistent Networks built in SQLite
Minor changes:
Least common denominator code now returns the portions of features that do not
overlap for both layers. Code is significantly slower for complex polygons, but
it now provides a complete result
Many consistency improvements
