        "modular to integer"
        SYNTAX: X = mtoi(a)

        a is an expression whose value is an element of Z/mZ, a
        polynomial over Z/mZ, a matrix or a vector over these
        structures, an elliptic curve or a point of an elliptic 
        curve over Z/mZ (where m is a prime).
        
        mtoi transforms the structures over Z/mZ into structures over Z.
        X is assigned the corresponding structure over Z.
        

        Example 1: (correct)

                mtoi({{MOD(3), MOD(23)} {MOD(2), MOD(100)}})


        Example 2: (correct)

                mtoi(PT(MOD(2), MOD(5), MOD(1)))


        Example 3: (incorrect)

                mtoi(x + y)
