Switch to Apple's BLAS implementation

[JeffreyEarly]

Following a blog post on using Apple's BLAS library you can switch with a simple environmental variable change.

With the Cyprus Eddy example, this dropped the computation time from 50 seconds to 33 seconds (run in the profiler), a 34% speedup. Interestingly, this completely flipped the rate-limiting computation from the matrix multiplications, to the FFTs.

Need to add a note about this.

Adding the attached file to your folder ~/Library/LaunchAgents/ should make the change permanent.
