Vec2

class Vec2(val x: Double, val y: Double) extends Vec2Like with ApproxDbl

A 2 dimensional vector. This is similar data to Pt2. The purpose of this separate type is to encode the relative nature of the Vec2 as opposed to the absolute nature of a Pt. So usually you will want and need to add the vector to an absolute point to return to the absolute realm of points. Thanks to René Descartes for this great idea.
