项目开始时只是一个新的尝试，看能否性能比httprouter更快。
近似零拷贝 只有在需要分配参数，才有可能从堆上分配内存。
高性能 现在某些指标和httprouter差不多
package main

}
func Hello(w http.ResponseWriter, r *http.Request, ps brouter.Params) {
fmt.Fprintf(w, "hello, %s!\n", ps.ByName("name"))
}
func main() {
router := brouter.New()
router.GET("/", Index)
router.GET("/hello/:name", Hello)
log.Fatal(http.ListenAndServe(":8080", router))
