Description

Add algorithm GeneralizeRoadNetwork for removing road lines close to reference lines and each other. The algorithm processes road classes one at a time, longest road features first within a class, and keeps a road if it is deemed far enough (long enough outside of buffered roads) from reference roads and kept network roads. Connectivity to (only) the reference road network is restored as the second step.

Notes:

• Some functionalities of this algorithm could maybe be moved into continuity module
• Roads and their lengths are processed as line segments which might produce unexpected/bad results in some cases
• Network connectivity is also checked against the reference road network, but should preserved roads that were originally separated from the reference road but connected together as their own mini network preserve their internal connectivity?
• I noticed the test data is rather large after pushing to GH, should it be cut down to some size?
