说明：  熟悉智能卡操作的朋友都知道微软的PC/SC规范提供了一个智能卡读卡器的标准，我在此之上封装了这个PCSC的类，用以执行对智能卡的连接，以及执行符合GSM11.11的APDU指令，希望对大家有所帮助
(familiar with the operation of the Smart Card friends all know Microsoft PC/SC standard provides a smart card reader standard accurate, and I would like to close the top of the PCSC category for the implementation of smart card connectivity, and the implementation of the Application Protocol Data Unit with GSM Directive, we hope to help)
