<p>The save file is stored at <code>GameSaves/save.dat</code> relative to the
directory containing the running JAR. The anchor class passed to the
constructor is used to resolve that directory at construction time.

<p>All three operations (<a href="#save(it.polimi.ingsw.gc14.Model.Game)"><code>save(Game)</code></a>, <a href="#load()"><code>load()</code></a>, <a href="#delete()"><code>delete()</code></a>)
are independent and safe to call in any order; missing files are treated
as a normal condition (no save present) rather than an error.</div>
