The current CUBLAS wrappers use the v2 interface because NVIDIA
dropped the v1 interfaces in the early 4.x shared libraries. I tried
to maintain v1-like Python interface to avoid breaking code that was
using it via the admittedly crude expedient of maintaining a global
library context variable to pass to the v2 function interfaces. Rather
than continue to propagate this situation, I'm going to modify the
wrapper to expose the v2 interface outright.

Sorry about the bounce, Freddie - that was due to a transient problem
with my mail that has since been fixed. Note that issues such as
development suggestions or requests regarding the toolbox can also
be reported on GitHub.
