(** * Some properties of the multiplication for modules implementing [NZBasicFunsSig']  This file defines the [NZMulProp] functor type on top of [NZAddProp]. This functor type is meant to be [Include]d in a module implementing [NZBasicFunsSig'].  This gives the following basic lemmas: - [mul_0_r], [mul_1_l], [mul_1_r] - [mul_succ_r], [mul_comm] - [mul_add_distr_r], [mul_add_distr_l] - [mul_assoc] - [mul_shuffle0] and [mul_shuffle3] to rearrange products of 3 terms - [mul_shuffle1] and [mul_shuffle2] to rearrange products of 4 terms  Notice that [NZMulProp] itself [Include]s [NZAddProp]. *)
