// = DESCRIPTION
// Interface code generation is complex, the client stubs require
// two different class and the server also require other two.
// Only one of them includes whatever nested typedefs, exceptions
// and or structures are defined in the interface.
// To break this complexity a different visitor is used for each
// case.
//
// = NOTE
// Visitors were added recently into the compiler, so some
// code is still generated using the old "state oriented" approach;
// notably only the _collocated class is actually generated using
// the visitor, in the other cases (the interface class and the
// skeleton class) we still call back the old code generation
// methods.
//
