included(/* parent */) {
    if (!this._addonsInitialized) {
      // someone called `this._super.included` without `apply` (because of older
      // core-object issues that prevent a "real" super call from working properly)
      return;
    }

    this.eachAddonInvoke('included', [this]);
  }
This method is called when the addon is included in a build. You
    would typically use this hook to perform additional imports

    #### Uses:

    - including vendor files
    - setting configuration options
Note:* Any options set in the consuming application will override the addon.

    @public
    @method included
    @param {EmberApp|EmberAddon} parent The parent object which included this addon

    @example
    ```js
    included(parent) {
      this._super.included.apply(this, arguments);
      this.import(somePath);
    }
    ```
