mbr:
    description:
        mbr(ket) sp
        returns the coeff of ket in the given superposition
        if ket is not in the sp then the returned coeff is 0

    examples:
        mbr(|b>) (|a> + |b> + |c>)
            |b>

        mbr(|c>) (0.3|a> + 2|b> + 9.7|c> + 13|d>)
            9.700000|c>

        mbr(|x>) (0.3|a> + 2|b> + 9.7|c> + 13|d>)
            0|x>
