function [a, b] = ransacLineFit_driver(a, c, npts, noise, outlier, nIter)
%
% test ransac line fit 
% y= ax + c (or b = -1)
% noise is level of noise (0 - 1)
% outlier is how many outlier points to add
% niter is how many iterations to try in ransacLineFit
% return [a, b]
% used in cs130b for programming assignment #4
% In the result, it will show the value for a and b.

Example: ransacLineFit_driver(10,35,7000,0.6,3000,500)
Result:a=10.2862; b=35.9361
