title: PetaPoco and Ignore attribute
body: <p>I have the following class:</p>
  
  <pre><code>public class Foo
  {
      public int Id { get; set; }
      ...
      public Boo Boo1 { get; set; }
      public Boo Boo2 { get; set; }
  }
  </code></pre>
  
  <p>I want to exclude <code>Boo1</code> and <code>Boo2</code> properties but I don't want to decorate those properties with <code>PetaPoco.Ignore</code> attribute. I want to have pure POCO objects. Can I execute <code>Ignore</code> command in code or do I have to create query/stored procedure and manually map all fields?</p>
  
  <p>Any help would be greatly appreciated!</p>
