    // Click pause
    // Initialize plugin using the plugin function on the player instance

enableTouchActivity()
Report user touch activity when touch events occur
User activity is used to determine when controls should show/hide. It's
relatively simple when it comes to mouse events, because any mouse event
should show the controls. So we capture mouse events that bubble up to the
player and report activity when that happens.
With touch events it isn't as easy. We can't rely on touch events at the
player level, because a tap (touchstart + touchend) on the video itself on
mobile devices is meant to turn controls off (and on). User activity is
checked asynchronously, so what could happen is a tap event on the video
turns the controls off, then the touchend event bubbles up to the player,
which if it reported user activity, would turn the controls right back on.
(We also don't want to completely block touch events from bubbling up)
Also a touchmove, touch+hold, and anything other than a tap is not supposed
to turn the controls back on on a mobile device.
Here we're setting the default component behavior to report user activity
whenever touch events happen, and this can be turned off by components that
want touch events to act differently.

not the actual computed width/height.

initChildren()

Add and initialize default child components from options
    // when an instance of MyComponent is created, all children in options
    // will be added to the instance by their name strings and options
    MyComponent.prototype.options_ = {
      children: [
        'myChildComponent'
      ],
      myChildComponent: {
        myChildOption: true
      }
    };

    // Or when creating the component
    var myComp = new MyComponent(player, {
      children: [
        'myChildComponent'
      ],
      myChildComponent: {
        myChildOption: true
      }
    });
The children option can also be an array of
child options objects (that also include a 'name' key).
This can be used if you have two child components of the
same type that need different options.
    var myComp = new MyComponent(player, {
      children: [
        'button',
        {
          name: 'button',
          someOtherOption: true

        'childTwo': {},
        'childThree': {}
