/**
* ## [launcher](com/launcher.js)
*
* displays app (icons) in 2D and 3D handmenu (enduser can launch desktop-like 'apps')
*
* ```html
* <a-entity launcher>
* <a-entity launch="component: helloworld; foo: bar"><a-entity>
* </a-entity>
*
* ```
*
* | property | type | example |
* |--------------|--------------------|----------------------------------------------------------------------------------------|
* | `attach` | `selector` | hand or object to attach menu to |
* | `registries` | `array` of strings | `<a-entity launcher="registers: https://foo.com/index.json, ./index.json"/>` |
*
* | event | target | info |
* |--------------|-------------------------------------------------------------------------------------------------------------|
* | `launcher` | an app | when pressing an app icon, `launcher` event will be send to the respective app |
*
* There a multiple ways of letting the launcher know that an app can be launched:
*
* 1. any AFRAME component with an `launcher`-event + manifest is automatically added:
*
* ```javascript
* AFRAME.registerComponent('foo',{
* events:{
* launcher: function(){ ...launch something... }
* },
* manifest:{ // HTML5 manifesto JSON object
* // https://www.w3.org/TR/appmanifest/
* }
* }
* ```
*
* 2. dynamically in javascript
*
* ```javascript
* window.launcher.register({
* name:"foo",
* icon: "https://.../optional_icon.png"
* description: "lorem ipsum",
* cb: () => alert("foo")
* })
* //window.launcher.unregister('foo')
* ```
*
