Implementation of tutorial found on

s2 = snell3d(n1,n2,s1,N)
n1,n2: refractive indexes of first medium and surface respectively
s1: incident ray vector (xyz vector, will be normalized and made column)
N: surface normal (xyz vector, will be normalized and made column)
s2: refracted ray (normalized xyz vector)
