它是一個多線程，多流程的腳本編譯解釋平臺，能夠同時運行多份類似于下面的腳本代碼：（流程可以直接加載任意接口的動態(tài)庫，執(zhí)行數(shù)據(jù)庫庫訪問，存儲過程和sql語句），加載支持雙借口的com.）
     它是一個通訊平臺，不同應(yīng)用程序（不論是否在同一臺機(jī)器）均可使用消息機(jī)制進(jìn)行同步或異步調(diào)用，不同程序的腳本之間也可以用這種機(jī)制進(jìn)行溝通，各模塊之間只需知道對方的模塊id和對象id即可，bus總線允許多個節(jié)點間進(jìn)行消息接力，應(yīng)用層不必關(guān)心。
    所有的腳本，所有的應(yīng)用程序模塊和對象均可以跑在總線上。
    總線類CDataBus，總線通訊對象CAsynWorker，總線流程對象CAWFlow
 
下面是總線控制腳本，你的應(yīng)用程序可以加載你自己的腳本和擴(kuò)展自己的腳本函數(shù)
腳本函數(shù)的定義在后面
