// each having a http server listening on its own port.
//
// The first "hello" is added to the restful.DefaultContainer (and uses DefaultServeMux)
// For the second "hello", a new container and ServeMux is created
// and requires a new http.Server with the container being the Handler.
// This first server is spawn in its own go-routine such that the program proceeds to create the second.
//
// GET http://localhost:8080/hello
// GET http://localhost:8081/hello
