UWSim-NET: UWSim with Network Simulator

The new version of UWSim intregates a Network Simulator to be used along with the dccomms API. This simulator uses the NS3 libraries and the AquaSimNG as a NS3 module. The documentation related to simulate communications is a work in progress and will be included in the Wiki as soon as we can (please, be patience).
