how koajs works @cc http://code.tutsplus.com/tutorials/introduction-to-generators-koajs-part-1--cms-21615
var koa = require('koa')();
koa.use(function* (next) {
//do something before yielding/passing to next generator function in line which will be 1st event in downstream
console.log("===1===");
console.log("A");
yield next;
// do something when the execution returns upstream, this will be last event in upstream
console.log("B");
