    Ok so the above line creates a reference to a stored object location. 
    It gives us the ability to read and write save data to somewhere we can retrieve it.

    We do this with key value pairs. Think of a dictionary where words reference 
    defentitions. 

    Word => Defention
    Car => A four wheeled vehicle.
    Key => Value

    In this case we're creating a StoredObject with the key '188'
