Facet in mesh
This is a facet in a MeshObject. You can get it by e.g. iterating a
mesh. The facet has a connection to its mesh and allows therefore
topological operations. It is also possible to create an unbounded facet e.g. to create
a mesh. In this case the topological operations will fail. The same is
when you cut the bound to the mesh by calling unbound().
