Comment:

 The legend widget certainly supports nesting groups within groups, but the
 problem I perceive is that MapServer itself has no mechanism to nest
 groups.  Layers can either belong to a group or not, but there is no way
 of doing this for groups.

 It is straight-forward to implement using some form of metadata in the map
 file, as long as we establish and document a convention for this and put
 support for it in LoadMap.php (support linking groups to parent groups).

 I would suggest that we support reading a "groupParent" metadata that can
 hold the name of a group for nesting in the legend.
