Detailed Description
The MeshRemoveNeedles class tries to fix degenerations by removing needles.
Needles are triangles where its longest edge is much longer than its shortest edge. https://graphics.uni-bielefeld.de/publications/vmv01.pdf

Construction.
The
- fMinEdgeLen must be in the range of 0.0 and 0.25. It defines the amount of perimeter of a triangle for which the shortest edge is considered for removal.
