//  Description:  This project is for dynamically balancing the traffic load 
//                  over a cellular network with fully adaptive antennas by 
//		    emulating the behaviours of a bubble array. Since 
//                  we assume fully adaptive base station antenna in this  
//                  version, antenna agent and simulator are not needed.
