As I wrote these bindings back in January, I wished for something
like both of these functions. Now that the CUDA Toolkit includes
them, I'm including them in these bindings.

I quickly double-checked the docs and made a few corrections. I'm
pretty sure they're ready to go into a testing phase. Once I have
some feedback, they'll go to CPAN!

I plan to release this to CPAN under CUDA::Minimal, not CUDA::Min,
since, as Chris Marshall pointed out, CUDA::Min could be ambiguous.
I am in the middle of this work, though, and I have not tested it.

It turned out that the internal function that determines whether
the piddle is a slice/mmap or not was always using a double for
its piddle, not the passed-in piddle's type. This led to datarefs
that were too long, and that led to all sorts of memory issues.
This set of corrections should fix that, though I'm not sure that
the test suite is fully up-to-date.
