docs: Creates Components as defined by the array of configurations _inInfo_.
  Each configuration in _inInfo_ is combined with _inCommonInfo_ as
  described in _createComponent_.
  
  _createComponents_ returns an array of references to the created components.
  
  ask foo to create components _bar_ and _zot_, but set the owner of
  both components to _this_.
  this.$.foo.createComponents([
  {name: "bar"},
  {name: "zot"}
  ], {owner: this});
