Reduce the Number of Points Defining a Curve

http://en.wikipedia.org/wiki/Ramer-Douglas-Peucker_algorithm
explains the Ramer-Douglas-Peucker algorithm for reducing the number of points 
in a curve that is approximated by a series of points.  Use random numbers to 
generate a curve and then use the algorithm to reduce the number of points.  

You may use

to draw the lines. 

You may use
http://mathworld.wolfram.com/Point-LineDistance2-Dimensional.html
to compute the distance from a point to a line.

By dividing the points into groups one could use multiple cores to improve 
the running time (if we had a lot of points).

Draw the original line and the final simplification.
