  2. * MicroEvent - to make any js object an event emitter (server or browser)
  3. *
  4. * - pure javascript - server compatible, browser compatible
  5. * - dont rely on the browser doms
  6. * - super simple - you get it immediately, no mystery, no magic involved
  7. *
  8. * - create a MicroEventDebug with goodies to debug
  9. * - make it safer to use
