/**
 * \file router_fabric.h For each bus functional model in the GreenBus framework, 
 * this file contains a convenience create method. These methods are used
 * by the configuration framework to created busses specified in the configuration file.
 * 
 * To add a new bus, three things are important:
 *  1. import all header files that are required by your bus
 *  2. add a line ADDBUS(yourBusName, yourBusProtocolClass, yourBusSchedulerClass) below.
 *  3. add a line busmap["yourBusName"] = create_yourBusName; in the createBusMap function below.
