isInStep: Given a position, a route, and a step index, determines if the position is close to the given step (within a customizable threshold).getDistanceToStep: Given a position, a route, and a step index, determines the distance between the position and the closest point in the given step.getSnapToRoute: Given a position, a route, and a step index, determines the closest point in the given stepisOffRoute: Given a position and a route, determines if the position is off-route (within a customizable threshold).getClosestStep: Given a position and a route, determines the closest step in the route.It also has a basic Activity to showcase its functionality.
