> Issue Type: New Feature

> We should add the following method to {{Vector2D}}:
> {code:java}
> public double signedArea(Vector2D v) { /* */ }
> {code}
> This method will return the signed area of the parallelogram formed by taking
> the current instance and the given vector as sides.
> This method should replace the existing {{cross}} method in {{Vector2D}}
> since it performs a similar operation and the cross product is not defined in
> 2 dimensions.
