**
** Executes a series of (user defined) operations when the `Registry` starts up. Operations are 
** defined by contributing listeners to the 'RegistryStartup' service. For example, add the 
** following to your module:
** 
**   @Contribute
**   static Void contributeRegistryStartup(OrderedConfig config, MyService myService) {
**     config.addUnordered |->| {
**       myService.startup()
**     }
**   }
**
