<P>
Implements the selection model for a graph.
This class fires the following events:
mxEvent.UNDO fires after the selection was changed in changeSelection. The
<code>edit</code> property contains the mxUndoableEdit which contains the
mxSelectionChange.
mxEvent.CHANGE fires after the selection changes by executing an
mxSelectionChange. The <code>added</code> and <code>removed</code>
properties contain Collections of cells that have been added to or removed
from the selection, respectively.
To add a change listener to the graph selection model:
<code>
addListener(
mxEvent.CHANGE, new mxIEventListener()
{
public void invoke(Object sender, mxEventObject evt)
{
mxGraphSelectionModel model = (mxSelectionModel) sender;
