public interface ReferenceManager
When transforming an input model into an output model, the developer needs to create relations between elements part of the output model
corresponding to relations part of the input model. However source and target elements might not yet exist in the output model by the time the
developer identifies the relations to create, depending on the navigation order in the input model. The ReferenceManager enables to
register references to create and to delay the actual creation by the time source and target elements exist in the output model.
It is the developer responsibility to execute a builder operation to create references in the output model. A build operation is to execute at least once at the end of the transformation. It shall be executed multiple times, at various stages of the transformation, if desired.
This interface is not intended to be implemented by clients.

Note that the builder operation will create references whose source and target elements exist in the output model. References whose source and target elements are not know by the time the operation is executed remain registered in the manager.
