title: What is a 'Bag' and a 'Set' in nHibernate?
body: <p>Using Fluent NHibernate, I come across the mapping <code>AsBag()</code> and <code>AsSet()</code> for <code>HasMany</code> and <code>HasManyToMany</code> relationships. I've done some searches, and I'm just not finding anything. Can anyone explain to me what these mean, and what the significance is?</p>
