demonstrate that equals goes hand in hand with compareTo
<p>It's written in all decent java courses, that if you implement the <code>Comparable</code> interface, you should (in most cases) <strong>also</strong> override the <code>equals</code> method to match its behavior.</p>

<p>Unfortunately, in my current organization people try to convince me to do exactly the opposite. I am <strong>looking for the most convincing code example</strong> to show them all the evil that will happen.</p>
