Challenge: Vector walker
Use PVector and vector addition to control a walker.
Animate the noise
Hint
var Walker = function() {
this. = new PVector(, );
};
This Walker uses separate properties, x and y, for the position. Change it so it stores a single position
property, a PVector, that behaves the same. You will need to change the constructor and the methods, since
they all use the position in some way.
