Scott has explained things in detail, but here's my short answer.
The first line gives you a business object that implements Retrievable.
The second line takes the properties from the bo and copies them to the
fields in an intake group. If the group has a field defined with the
name = "Foo" then you could use this in a form:
<input type="text" name="$group.Foo.Key" value="$group.Foo" />
