Compute the coefficients of the Laguerre polynomial, given the order. We calculate the Laguerre polynomial using the recurrence relations, Ln+1(x) = inv(n+1)*((2n+1-x)Ln(x) - nLn-1(x)).
If the value x is specified, the polynomial is also evaluated, otherwise just the return the coefficients of the polynomial are returned.
This is NOT the generalized Laguerre polynomial.
