ModNewt:
-------------------------------------------------------------------------------
Finds the solution to f(x) = 0 given derivative information.
Uses df(x)/dx when only one root is possible. If there are multiple roots,
x should be in the vicinity of the desired root.
-------------------------------------------------------------------------------
Form:
[x, n] = ModNewt( f, fD, fDD, x, epsilon, nMax, varargin )
