Generating spiral sample
spiralData.Rdn-2 points are drawn from a normal distribution with mean=0, sd=1, the points in the final two direction are sampled along a spiral by samping the angle from a normal distribution with mean=0, sd=2*pi (absolute values are used to fix the orientation of the spiral).
