2 /* This module includes utilities that operate on single knots. It builds
3  structures where the knots can be saved, it finds boundaries,
4  copies knots from structures to others and destroys structures that
5  become obsolite. The routines mostly operate on structures
6  FemType and BoundaryType. */
