errorsOut should contain any errors that were encountered within
FooInitialize. I just can't figure out how to get errorsOut to refer to
a PERL array.
I've been reading swig and perl documentation all day today and I can't
find anything. I think I've figured out the char** arg_list because I've
edited the wrapped code to print out the value of *arg2 and all looks
Also, am I accessing the function the correct way from perl (by passing
the arrays as references)?
