Write a function that uses the Newton Raphson iteration to solve for log(b).

Note that f(x) = 0 at x = log(b).

function [y,terms] = NR_log( x, MaxTerms )

%

% [y,terms] = NR_log(x, MaxTerms )

%

% Computes log of the number x, using a MaxTerms terms.

%

% Input: x Number that we want the natural log of.

% MaxTerms The maximum number of terms that are to be used.

% [default: 1000]% Output: y log of x

% terms number of terms used.
