-   *       c: 0

-   * let example = this._ensureObjectChain([a, b, c], 0);

-   * Subsequent repetitions of these last two lines would
-   * simply result in the c value being incremented again

-   *
-   * @param aKeys the Array of keys to chain Objects together with.

-   * @param aRoot the root object onto which we create/get the object chain
