Good to know -- would you recommend installing zlib1.dll into the
pynifti installation dir by default? In that case I'd adjust the docs.

If you built whole Python with MSVC, can I assume that you also built
pynifti with it? I'd also like to mention that in the docs. Was anything
special necessary to do that?
