# I need to match paths like:
#
# /templates/foo/bar                    {:controller => 'templates', :id => 'foo/bar'}
# /templates/foo/bar/questions          {:controller => 'questions', :template_id => 'foo/bar'}

# The commented-out routes match ok, but the #resources for does not, 
# using both :id => /.+/ and the lookahead I have in there now.
