<DD>This method is used when you want to short circuit a Screen and
 change the template that will be executed next. <b>Note that the current
 context will be applied to the next template that is executed.
 If you want to have the context executed for the next screen,
 to be the same one as the next screen, then you should use the
 TemplateScreen.doRedirect() method.</b><DD><DL>

<DL>
<DD>You can call this within a Screen to cause an internal redirect
 to happen.  It essentially allows you to stop execution in one
 Screen and instantly execute another Screen.  Don't worry, this
 does not do a HTTP redirect and also if you have anything added
 in the Context, it will get carried over.

 <p>

 This class is useful if you have a Screen that submits to
 another Screen and you want it to do error validation before
 executing the other Screen.  If there is an error, you can
 doRedirect() back to the original Screen.<DD><DL>
