[Haskell] Generator Function for Prime Numbers

[Jacques Carette]

And yet Taral would be wrong and Dave Feustel correct:
http://mathworld.wolfram.com/Prime-GeneratingPolynomial.html

There is a polynomial (of degree 25) in 26 variables which generates 
only primes whenever it is positive.  Surprising, yes it is.  Note that 
this polynomial is actually rarely positive!
