Calculates first derivatives of Legendre polynomials and returns them
    in a dictionary ``Pnprime``.

    :param float x:     argument to calculate first derivate of Legendre polynomials
    :return Pn:         dictionary which contains order of Legendre polynomials
                        (from 0 to 4 and even numbers until 14) as keys and
                        the corresponding evaluation of first derivative of
                        Legendre polynomials as values.
