-     public class Container
      extends Object

  Container. This class allows a containment events to be generated from update methods. The style of usage is:

         {
             getContainer().update(this,this.foo,foo,"foo");
             this.foo=foo;
         }

         public void setBars(Bar[] bars)
         {
             getContainer().update(this,this.bars,bars,"bar");
             this.bars=bars;
         }

    - #### addEventListener

          public void addEventListener(Container.Listener listener)

    - #### removeEventListener

          public void removeEventListener(Container.Listener listener)

    - #### update

          public void update(Object parent,
                    Object oldChild,
                    Object child,
                    String relationship)

      Update single parent to child relationship.
      Parameters:
        `parent` - The parent of the child.
        `oldChild` - The previous value of the child. If this is non null and differs from `child`, then a remove event is generated.
        `child` - The current child. If this is non null and differs from `oldChild`, then an add event is generated.
        `relationship` - The name of the relationship

    - #### update

          public void update(Object parent,
                    Object oldChild,
                    Object child,
                    String relationship,
                    boolean addRemove)

      Update single parent to child relationship.
      Parameters:
        `parent` - The parent of the child.
        `oldChild` - The previous value of the child. If this is non null and differs from `child`, then a remove event is generated.
        `child` - The current child. If this is non null and differs from `oldChild`, then an add event is generated.
        `relationship` - The name of the relationship
        `addRemove` - If true add/remove is called for the new/old children as well as the relationships

    - #### update

          public void update(Object parent,
                    Object[] oldChildren,
                    Object[] children,
                    String relationship)

      Update multiple parent to child relationship.
      Parameters:
        `parent` - The parent of the child.
        `oldChildren` - The previous array of children. A remove event is generated for any child in this array but not in the `children` array. This array is modified and children that remain in the new children array are nulled out of the old children array.
        `children` - The current array of children. An add event is generated for any child in this array but not in the `oldChildren` array.
        `relationship` - The name of the relationship

    - #### update

          public void update(Object parent,
