Initializes the schema for the specified type in the data model.
<p>
The schema will be derived from the field and type names in
<code>clazz</code> and added to the state engine's data model;
schemas of types referenced from <code>clazz</code> will also be added.
This can be used to add a type's schema to the state engine
without having to add any data for that type.
