Skyhop.SpatialMap (nuget): This package contains a data type which supports projection of an object onto a 2D X/Y grid. It is meant to quickly locate objects around a certain coordinate, and doesn't support lookup by values. This object is implemented on top of the SortedList type and therefore uses a binary search for object location.
