[jira] [Created] (GEOMETRY-42) Vector2D signedArea() Method

Matt Juntunen created GEOMETRY-42:
-------------------------------------

             Summary: Vector2D signedArea() Method
                 Key: GEOMETRY-42
                 URL: https://issues.apache.org/jira/browse/GEOMETRY-42
             Project: Apache Commons Geometry
          Issue Type: New Feature
            Reporter: Matt Juntunen


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.
