<overview>
<p>Dead methods are often deprecated pieces of code, and should be removed as they may increase 
object code size, decrease code maintainability, and create the possibility of misuse. A method is 
considered dead if it is private and not directly called, or accessed, or only ever called from 
other dead methods.</p>

</overview>
<recommendation>
<p>Consider removing the method or cluster of methods.</p>

</recommendation>
<example>
<p>Both private methods in this example are dead. <code>A</code> is dead because it is never called 
and <code>B</code> is dead because it is only called from the dead method <code>A</code>.</p>
