Pair

public struct Pair
extension ClosedShape2Intersection.Pair: Equatable where Vector: Equatable
extension ClosedShape2Intersection.Pair: Hashable where Vector: Hashable

A pair of entrance/exit intersection points.

The definition of entrance/exit is dependant on the shapes intersected, and the only requirement is that within the same ClosedShape2Intersection, each pair is expected to be connectable entrance-to-exit with its succeeding pair.
