Much of the Node.js core API is built around an idiomatic asynchronous event-driven architecture
in which certain kinds of objects (called "emitters") emit named events that cause Function objects
("listeners") to be called.

staticonce<T>(emitter:IEventEmitter, name:Event<T>):Promise<Array<Dynamic>>
Creates a Promise that is resolved when the EventEmitter emits the given
event or that is rejected when the EventEmitter emits 'error'.
The Promise will resolve with an array of all the arguments emitted to the
given event.
