[vtkusers] requirements for Python wrapping

[tom fogal]

I have some in a C++ object that is not getting wrapped into python for some
reason.

What are the requirements for a function to be wrapped into other languages,
python specifically? In Wrapping/Python/README_WRAP.txt it says that a
function will not be wrapped if it returns a pointer to an array; the function
in question takes a pointer to an array as an argument, so I'm wondering if
perhaps the wrappper-generating program needs some kind of alternative 'hint' ?

Thanks,
