 | <p>A string representation of this object.</p> | 
 | <p>Some classes have a default textual representation, | 
 | often paired with a static <code>parse</code> function (like <code>int.parse</code>). | 
 | These classes will provide the textual representation as | 
 | their string represetion.</p> | 
 | <p>Other classes have no meaningful textual representation | 
 | that a program will care about. | 
 | Such classes will typically override <code>toString</code> to provide | 
 | useful information when inspecting the object, | 
 | mainly for debugging or logging.</p> |
