<p>
For this task, I used an <kbd>enumeration</kbd> to, contain all 32-points of the compass.<br />
The bounds and mid-points can then be derived using the <code>enum</code> ordinal value.
</p>
<p>
The <code>toString</code> method breaks down the <kbd>enum</kbd> name into characters, and
replaces each with there corresponding written value.
