NAME

       freefoam-surfaceSplitNonManifolds - Takes multiply connected surface and tries to split
       surface at multiply connected edges by duplicating points.

SYNOPSIS

       freefoam surfaceSplitNonManifolds <Foam surface file> <surface output file> [-case <dir>]
       [-srcDoc] [-debug] [-doc] [-help]

DESCRIPTION

       Introduces concept of - borderEdge. Edge with 4 faces connected to it. - borderPoint.
       Point connected to exactly 2 borderEdges. - borderLine. Connected list of borderEdges.

       By duplicating borderPoints this will split borderLines. As a preprocessing step it can
       detect borderEdges without any borderPoints and explicitly split these triangles.

       The problems in this algorithm are: - determining which two (of the four) faces form a
       surface. Done by walking face-edge-face while keeping and edge or point on the borderEdge
       borderPoint. - determining the outwards pointing normal to be used to slightly offset the
       duplicated point.

       Uses sortedEdgeFaces quite a bit.

       Is tested on simple borderLines resulting from extracting a surface from a hex mesh. Will
       quite possibly go wrong on more complicated border lines (i.e. ones forming a loop).

       Dumps surface every so often since might take a long time to complete.
