/** @HTML
Helper class for implementing the <code>XDispatchProvider</code> interface
of the ChartController. This class handles all commands to queryDispatch and
queryDispatches in the following way:
<ul>
<li>Check if there is a cached <code>XDispatch</code> for a given command.
If so, use it.</li>
<li>Check if the command is handled by this class, e.g. Undo. If so,
return a corresponding <code>XDispatch</code> implementation, and cache
this implementation for later use</li>
<li>Otherwise send the command to the chart dispatch provider, if it
can handle this dispatch (determined by the list of commands given in
<code>setChartDispatch()</code>).</li>
</ul>
<p>The <code>XDispatch</code>Provider is designed to return different
<code>XDispatch</code> implementations for each command. This class here
decides which implementation to use for which command.</p>
<p>As most commands need much information of the controller and are
implemented there, the controller handles most of the commands itself (it
also implements <code>XDispatch</code>). Therefore it is set here as
chart dispatch.</p>
