Comparing List to List with a Twist
<p>I want to compare two List of different lengths and/or same length. The first list is considered the Original list. The 2nd list is the Updated list. The second list may be the same but ordered differently.</p>

<p>I would like to keep track of additions and subtractions from the list. If something was removed it could be added to a removed collection and vice versa.</p>

<p>Below is an example of each list with an input</p>

<pre><code>Original List    Updated List
=============    ============
Jim              Tom
Tom              Mike
Mike             Harry
Sue              Sue
Kim              Roger
Roger
</code></pre>

<p>This is an desired output:</p>

<pre><code>Addition List    Subtraction List
=============    ================
Harry            Jim
                 Kim
</code></pre>

<p>If you have Ideas I would be glad to hear them!   </p>
