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

*

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

* @param aRoot the root object onto which we create/get the object chain
|
|
* designated by aKeys.
|
|
* @returns a reference to the second last object in the chain -
|

* so in our example, that'd be "b".
