code: public Binding createBoundShuttleList( String selectionFormProperty, Object selectableItems ) {
          return createBoundShuttleList(selectionFormProperty, new ValueHolder(selectableItems), null);
      }
docs: Binds the values specified in the collection contained within
  <code>selectableItems</code> (which will be wrapped in a
  {@link ValueHolder} to a {@link ShuttleList}, with any user selection
  being placed in the form property referred to by
  <code>selectionFormProperty</code>. Each item in the list will be
  rendered as a String.
  <p>
  Note that the selection in the bound list will track any changes to the
  <code>selectionFormProperty</code>. This is especially useful to
  preselect items in the list - if <code>selectionFormProperty</code> is
  not empty when the list is bound, then its content will be used for the
  initial selection.
  
  @param selectionFormProperty form property to hold user's selection. This
  property must be a <code>Collection</code> or array type.
  @param selectableItems Collection or array containing the items with
  which to populate the selectable list (this object will be wrapped
  in a ValueHolder).
  @return constructed {@link Binding}. Note that the bound control is of
  type {@link ShuttleList}. Access this component to set specific
  display properties.
