Virtual method Generated is redefined. Now it returns: - chain of generated faces for sub-edge of a profile; - chain of generated edges for sub-vertex of a profile; - bunch of chains of generated edges for start or end vertex if it is degenerated section. Correction according to the remarks. Fix compiler's warnings and add 4 new test cases. Correction of mistake. Compilation warnings are gone.
