Given a list of points (x, y), GestureSimplifyJS removes points but aims to keep the integrity of the shape of the line. It does this by iterating over the list and removing the points that fall under a given distance and angle threshold. These thresholds are increased with each iteration until the stopping criteria is satisfied, that is, when the list length is less than a given constant.
See demoDriver.html for an implementation example.
