[fusion-users] Multiple Maps and OverviewMap.

[Mike Adair]

The MapMenu will load in a new MapGroup object into the MapWidget (the 
MapWidget and MapMenu must be in the same WidgetSet in AppDef).  By 
default the menu lists all the MapGroup objects found in AppDef, but you 
can also point it to a folder resource in MapGuide like 
<Folder>Library://some/folder</Folder> to list all the MapDefinition 
resources in that folder.
