title: how to compare two arrays of objects
body: <p>i have an object called <strong>Person</strong>.  It has properties <strong>First, Last, Age</strong>, etc . . .</p>
  
  <p>I have two arrays of Person objects.</p>
  
  <p>I want to have some function to take two arrays</p>
  
  <pre><code>Person[] firstlist =  . .
  Person[] secondList =  . . 
  </code></pre>
  
  <p>and have it spit out two new arrays</p>
  
  <pre><code>Person[] peopleinFirstListandNotSecond
  Person[] peopleinSecondListandNotFirst
  </code></pre>
  
  <p>Since these are not string arrays, i would want to do a compare on first and last name and age to determine if its the same person</p>
