    [torque] Clarify class annotations · 4dc59509
    Seth Brenith authored
    As Nico pointed out in [1], it is a little strange that the pair of
    annotations "@export @customCppClass" behaves similarly to the keyword
    "extern": both indicate that the class is defined in a C++ file and
    Torque generates only a base class template for it. In this change, I
    explore a possible alternative which might be more consistent.
    
    Removed annotations:
    - @customCppClass, which required @export, instructed Torque to only
      generate a base class template instead of a full class.
    - @customMap, which also required @export, instructed Torque to not emit
      code for setting up a unique Map instance for the class.
    
    Added annotations:
    - @generateUniqueMap, which requires extern, instructs Torque to emit
      code for setting up a unique Map instance for the class.
    - @generateFactoryFunction, which requires extern, instructs Torque to
      emit a function for creating a class instance.
    
    Subtracting two annotations and adding two others still leaves us with
    way too many annotations, but the usage of "extern" becomes more
    consistent and I think that the new opt-in annotations might be easier
    to understand.
