Detailed Description

Container of info needed to solve problems with internal shapes.

Issue 0020676. It is made up as a class to be ready to extract from NETGEN and put in SMESH as soon as the same solution is needed somewhere else. The approach is to precompute internal edges in 2D and internal faces in 3D and put their mesh correctly (twice) into netgen mesh. In 2D, this class finds internal edges in faces and their vertices. In 3D, it additionally finds internal faces, their edges shared with other faces, and their vertices shared by several internal edges. Nodes built on the found shapes and mesh faces built on the found internal faces are to be doubled in netgen mesh to emulate a "crack"

For internal faces a more simple solution is found, which is just to duplicate mesh faces on internal geom faces without modeling a "real crack". For this reason findBorderElements() is no more used anywhere.
