ryan schmidt c3195967aa ModelingTools: add new FindPolygons Algorithm based on furthest-point sampling on surface. ...

- add optional support for distance-weighting/modulation in TMeshDijkstra. Replace previous FVector2d seed points w/ new FSeedPoint struct that provides an external ID. Track seed point source through graph propagation, add GetSeedExternalIDForPointSetID() to look up seedpoint source external ID for any computed point.
- add new TIncrementalMeshDijkstra, variant that supports incremental update (ie adding new seed points) of a dijkstra graph-distance solution. This variant assumes solution will be computed across the entire graph, so dynamic allocation of nodes is not supported, full set is allocated/initialized on graph initialization.
- Add new method to FFindPolygonsAlgorithm that generates face groups derived from approximate surface-voronoi diagram, computed based on a point set found by (approximate) incremental furthest-point sampling.
- Add optional min-group-size to FFindPolygonsAlgorithm, groups smaller than the given criteria will be appended to largest neighbouring group
- Expose above additions in ConvertToPolygonsTool
