[mapguide-users] create a temporary !Mapdefinition and add a layer

The "Target" stuff refers to clicking on a link on a feature.
The PHP code below only relocates the current page.
This means that the new window is created *before* the
code below is being run. Try locating that spot,
and change the target to "_top" or "_self".
For explanation on the targets, look here:
http://www.codetoad.com/html/frames/specifying_frames.asp
If you are actually modifying the WebLayout when clicking a feature,
the target should probably be set to "_parent" in Maestro.
After setting the target, press the "View Xml" button to
see what changes your code has to make to achieve the same.
