title: Class method vs main methods
body: <p>I'm rather confused by the concept of making a class with methods, and having a main method with methods underneath.</p>
  <p>What exactly are the differences here? How it one way better than the other way? What situations call for a method under the main rather than a class?</p>
  <p>It would help me to understand a project -  a basic Craps game which will contain a Shooter class, Die class, and a Craps class (which apparently contains the main).</p>
