Function S2Region.mayIntersect

If this method returns false, the region does not intersect the given cell. Otherwise, either region intersects the cell, or the intersection relationship could not be determined.

abstract bool mayIntersect (
  in const(S2Cell) cell
);

Note that there is currently exactly one implementation of this method (S2LatLngRect::MayIntersect) that takes advantage of the semantics above to be more efficient. For all other S2Region subtypes, this method returns true if the region intersect the cell and false otherwise.
