Need to detect cycles when creating complex anonymous types.

[wekempf]

public class Foo
{
    public Bar Bar { get; set; }
}

public class Bar
{
   public Foo Foo { get; set; }
}

…

anon.Any<Foo>(PopulateOption.Deep); // Results in an OutOfMemoryException

AnonymousData should detect cycles and react to them. Possible options, that maybe should be configurable behavior by the caller.

1. Throw an exception that provides information about the cycle.
2. Simply don't populate the property that causes the cycle.
3. Populate the property with the "parent" value.
