Nova fractal

The Nova fractal was created by Paul Derbyshire while estimating the Newton fractals. Paul Derbyshire modified the Newton's method in order to improve the the rate of convergence. The Nova fractal is derived from this equation zn+1 = zn - R * f(zn) / f '(zn) while the initial function was f(z) = zp-1, and therefore the equation that is iterated  zn+1 = zn - R (znp - 1) / (p znp-1) + c
