New description:
Improve the error analysis for the implementation of Dobinski's formula to
compute the Bell numbers leading to
1. code which is actually consistent with the mathematical formulas
1. code which is cleaner and simpler than before, hopefully slightly
faster
1. a complete error estimate including the final real approximation
