Careful.
SWIG does not create instantiations of templated classes whenever
it sees a templated class reference (say, as a return type, or
in a parameter list).
The %template directive results in a templated class instantiation
that will actually be seen by <LANG> :: classHandler().
In this case, we don't want to error if the type already exists;
the point is to force the creation of wrappers for the templated
class.
