NewtonIters
-----------
This function calculates the n-th root of -1 ie. z^n-1=0, using the
Newton-Raphson method. Floating point arithmetic is required so don't expect
it to zip along. This function plots the colour based on the iteration count.
There are 2 data variables:
Max Iter : iteration limit.
e : The accuracy check value. The iteration is stopped when a root is found
that solves the equation to within the 'e' accuracy value. Higher values of
'e' force greater accuracy and more iterations to be used, useful when
zooming in.
A 3d version can be drawn directly by turning on the 3d X/Y Plot option.
See the 3d section of !MainHelp for details.
Thanks to Joyce Haslam for providing this function.
