[mapguide-users] modifying map before the WebLayout loads

[David Hequet]

hum ok, my code miss this:

Load WebLayout
Modify WebLayout to point to session map
Save WebLayout in session repo
Open viewer pointing to WebLayout in Session repo 

Since there is no API to access WebLayout, i dont know how to acces/modify
the Layout.
Thank you!
