RegisterMismatchCuda error on import

[Cody-G]

The error is introduced by commit d78cef4 (Femtocleaner!)

Here's the message. It can be triggered with using BlockRegistration; using RegisterMismatchCuda

Of course you'll need a GPU machine like cannon to trigger the error.

I fixed this by dropping the Femtocleaner commit for now, see the branches julia0.6 and cjg/fix_cuda. Moreover the CUDA code actually works on 0.6 now.

Awesome!

Can this be closed or is there something else to merge?

[Cody-G]

This commit is now only on the julia0.6 branch but I expect we'll want to bring that commit into master for 0.7 at some point. Likewise this commit that introduced a text guide to CUDA environment setup. But we already have an issue for CUDArt trouble (#76) so I think we can close this one.
