NewtRaph:
-------------------------------------------------------------------------------
Finds the solution to f(x) = 0 given df(x)/dx when only one
root is possible. If there are multiple roots, x should be in the
vicinity of the desired root.
Accepts up to 10 optional arguments that are passed through to f and fD
-------------------------------------------------------------------------------
Form:
[x, n] = NewtRaph( f, fD, x, epsilon, nMax, varargin )
-------------------------------------------------------------------------------

varargin Optional arguments
-------
Outputs
-------
