Compute all the orthonormalized Legendre polynomials.
p = PlON (lmax, z)
p : float, dimension (lmax+1) : An array of orthonormalized Legendre polynomials up to degree lmax. Degree l corresponds to array index l.
lmax : integer : The maximum degree of the Legendre polynomials to be computed.
z : float : The argument of the Legendre polynomial.
PlON will calculate all of the orthonormalized Legendre polynomials up to degree lmax for a given argument. These are calculated using a standard three-term recursion formula. The integral of the orthonormalized normalized Legendre polynomials over the interval [-1, 1] is 2/(4pi).
