Lazy import of numpy in setup.py

[cHYzZQo]

Allows this package to bring it in as a dep instead of forcing it to be installed already.

[cHYzZQo]

Running locally I get the same test failures on master as travis shows on this branch. Are the failures a known issue? Or caused by the setup changes?

Thanks for working on this! It looks good, the test failures appear to be caused by the blas / lapack libraries not getting linked in correctly, which seems to suggest that the finalize_options method is not doing what it's meant to. I tried to fix it but I couldn't figure out how to get the extra options created there to be used. Locally, you can see this by running nosetests -s, which doesn't capture stdout, and you will see a lot of error messages like:

Hmm, that means that when i build master locally I'm also not linking in correctly. Does master work for you?

[bodono]

Master works for me, yes.

[cHYzZQo]

Got the tests to pass by moving the list settings down to the build_extension level.

[bodono]

Awesome, thanks!

[cHYzZQo]

Thanks for merging. Any idea when this will be available in pypi?

[bodono]

Up now.
