* Changed DERIV_intros to a NamedThmsFun. Each of the theorems in DERIV_intros assumes composition with an additional function and matches a variable to the derivative, which has to be solved by the simplifier. Hence (auto intro!: DERIV_intros) computes the derivative of most elementary terms.
* Maclauren.DERIV_tac and Maclauren.deriv_tac was removed, they are replaced by: (auto intro!: DERIV_intros) INCOMPATIBILITY. DERIV_tac, deriv_tac, and DERIV_intros is not used in AFP. When someone has private theories using this tactices, could you please try to replace it with (auto intro!: DERIV_intros)? Johannes
