// Notes: 
// * Add here stubbed implementation of the few classes and methods used in the class to be tested
// * Add as little as possible (let the link errors guide you)
// * Do not make any assumption as to how those classes or methods work (i.e. don't copy/paste code)
// * A simulator for a class can be implemented here. Please comment and document thoroughly.
