The first step of "agent" has almost completed ,just achieve the basic

function of agent.
Primarily rewrite my agent code refer to seniors' code,achieve the simple communication between the client and server.The next step is to achieve that the server can accepts task flows and then deal with fork and exec.

虽然这只是测试程序，也尽量避免“凑合”式的代码。　定义一个描述task结构体！
