#
# In case that node-config -addressType hierarchical is not called, and 
# the old way of Simulator set node_factory_ HierNode is used.

# for now creating a new class for hier-node for the sake of minimum overlap. 
# However this may be combined with ns-node at a later date when hierarchical
# routing gets to become stable & operational.
