```
public void mousePressed(java.awt.event.MouseEvent e)
```
    save the 'down' point and check the modifiers. If the modifiers are accepted, set the cursor to the 'hand' cursor
    
    Specified by:
    
    mousePressed in interface java.awt.event.MouseListener
    
    Parameters:
    e - the event
  - mouseReleased
```
public void mouseReleased(java.awt.event.MouseEvent e)
```
    unset the down point and change the cursor back to the default
    
    Specified by:
    
    mouseReleased in interface java.awt.event.MouseListener
  - mouseDragged
```
public void mouseDragged(java.awt.event.MouseEvent e)
```
    check the modifiers. If accepted, use the mouse drag motion to rotate the graph
    
    Specified by:
    
    mouseDragged in interface java.awt.event.MouseMotionListener
  - angleBetween
```
protected double angleBetween(java.awt.geom.Point2D v1,
                  java.awt.geom.Point2D v2)
```
    Returns the angle between two vectors from the origin to points v1 and v2.
