Detailed Description

Use a Voronoi diagram to support faster querying of Voronoi-like data from arbitrary sample points:

• Distance to closest point
• ID of closest point
• IDs of closest two points
• Distance to closest Voronoi cell boundary (not considering bounding box walls)

Note: Queries are only thread safe if each thread has its own FVoronoiComputeHelper
