Gaute Lindkvist 03cfa8f146 #3644 Move hex overlap code to RigCellGeometryTools and clamp in z-direction as well.
* The latter is not important for 2d Maps because the height of the 2d extrusion is always at least as much as the cells.
* However this makes it so the code can estimate overlap with bounding boxes that do not reach the full height of the hexahedron.
* Also added unit tests.
