Detailed Description

The MeshFixCaps class tries to fix degenerations by swapping the common edge of a cap and its neighbour.

Caps are triangles with one angle close to 180 degree. The definitions of caps and needles are not mutually exclusive but here we only consider triangles that are caps but no needles. https://graphics.uni-bielefeld.de/publications/vmv01.pdf
