Automapper returning an empty collection, I want a null
<pre><code>public class Person
{
   Name { get; set; }
   IEnumerable&lt;Address&gt; Addresses { get; set; }
}

public class PersonModel
{
   Name { get; set; }
   IEnumerable&lt;AddressModel&gt; Addresses { get; set; }
}
</code></pre>

<p>If I map <code>Person</code> to <code>PersonModel</code> like so:</p>

<pre><code>Mapper.DynamicMap&lt;Person, PersonModel&gt;(person);
</code></pre>

<p>If the <code>Addresses</code> property on <code>Person</code> is null they are mapped on <code>PersonModel</code> as an empty <code>Enumerable</code> instead of null.</p>

<p>How do I get <code>PersonModel</code> to have null <code>Addresses</code> instead of an empty <code>Enumerable</code>?</p>
