Class KoalaVector

java.lang.Object
  koala.KoalaVector

public class KoalaVector
extends java.lang.Object

Represents a 2D vector, which is a line with magnitude and direction. Class essentially exists to encapsulate the all-pervasive vector calculations. The geometric convention at work here is that +x is to the right, +y is to the top, and +direction is anti-clockwise (the usual convention). Angles are in degrees.
