Decorators aren't applied to templated types

[tadfisher]

Writing an emitter for a target language that understands template arguments, I want decorators to apply to the template type itself so I can change how the type is emitted; for example, changing a model's field names. Currently my decorator function is called only for the derived types, so I will see several stateMap entries for "finished" versions of the template type and not the template type itself. The cause of this was difficult to track down and rather confusing.

This is by design, templates are only available as instance in any reference.

Most decorators also will not expect receiving a non finished template, leading in crashes.

It does seem however we are lacking this in our template documentation.
