Function cuboid_segment_find_local_separating_edge_twoway 

pub fn cuboid_segment_find_local_separating_edge_twoway(
    cube1: &Cuboid,
    segment2: &Segment,
    pos12: &Isometry<f64>,
) -> (f64, Vector<f64>)

Finds the best separating edge between a cuboid and a segment.

All combinations of edges from the cuboid and the segment are taken into account.
