 *
 * const emitter = emitterFor(httpTransport("http://example.com"));
 * emitter.emit(myCloudEvent)
 *    .then(resp => console.log(resp));
 *
 * @param {string|URL} sink the destination endpoint for the event
 * @returns {TransportFunction} a function which can be used to send CloudEvents to _sink_
