Description
Patches (regionises) a surface using a user-selectable method.
The current methods are either based on a geometric feature angle
(a replacement for the surfaceAutoPatch functionality) or on intersecting
a set of searchableSurfaces - this will re-triangulate the intersecting
triangles and regonise the resulting triangles according to being
inside/outside the surface.
