     * (1) if a string or number, the value is returned as a string; or

     * (3) if it is an object, it traverses the object and nested ones recursively
     * 		based on the `potentialKeys` and returns a string if found.
     *
     * If nothing found via `potentialKeys` this method iterates over `traversalKeys` and
     * if the value at the key is a traversable object, it restarts with the object as the

     * `traversalKeys`.

     * returned.
