uDig should recognized organized directories of shapefiles

Some data sets are distrbuted as hierarchies of folders in which shapefiles are present. UDig should recognize this when it is pointed at a directory and provide users with a list of candidates.

For example, the frech BD_Carto sample product available here
http://www.ign.fr/rubrique.asp?rbr_id=2407&lng_id=FR
in its shapefile incantation, is organzied hierachically:

BD_CARTO>
ADMINISTRATIF/
EQUIPEMENT/
HABILLAGE/
HYDROGRAPHIE/
RESEAU_FERRE/
RESEAU_ROUTIER/
TOPONYMIE/

with each directory holding several shapefile groups. uDig should do the minimal amount of crawling to recognize the layout and provide the user with a straight forward way to import all or some of the files.
