  11 `core-signals` provides basic publish-subscribe functionality.
  12
  13 Note: avoid using `core-signals` whenever you can use
  14 a controller (parent element) to mediate communication
  15 instead.
  16
  17 To send a signal, fire a custom event of type `core-signal`, with
  18 a detail object containing `name` and `data` fields.
  19
  20     this.fire('core-signal', {name: 'hello', data: null});
  21
  22 To receive a signal, listen for `core-signal-<name>` event on a
  23 `core-signals` element.
  24
  25   <core-signals on-core-signal-hello="{{helloSignal}}">
  26
  27 You can fire a signal event from anywhere, and all
  28 `core-signals` elements will receive the event, regardless
  29 of where they are in DOM.
