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.
