* --Preventing parent/child hierarchy creation loops - Comment 1--
* Creating a parent model will result in the creation of child models. Creating a child model will result in

*
* By checking whether a model has already been resolved (as implemented below), loops of parents creating
* children and children creating parents can be short-circuited. This works because currently the
* ModelConverterContextImpl will return null for a class that already been processed, but has not yet been
* defined. This logic works in conjunction with the early immediate definition of model in the context
* implemented later in this method (See "Preventing parent/child hierarchy creation loops - Comment 2") to
