DistantPointDetector Class
This class contains the logic for finding the best candidate among a series of colliders.
It uses up to three conical frustums from DistantPointDetectorFrustums for selection and deselection.
bool ComputeIsPointing ( Collider[] colliders,
bool isSelecting,
out float bestScore,
out Vector3 bestHitPoint )
bool IsPointingWithoutAid ( Collider[] colliders,
out Vector3 bestHitPoint )
bool IsWithinDeselectionRange ( Collider[] colliders )
