Sleef

[s-cavalier]

Currently there is no explicit SIMD usage. We use SLEEF to utilize explicit SIMD math functions.

Action items:

• Implement SLEEF into the current system. Prefer CMake if possible. If not, make it clear how to use on linux/mac. Windows not necessary.
• Write some wrappers to implement with the current Tensor/Expression system. There are a couple ways to approach this, ask if need be
• Ideally all of the wrappers should follow a single operator()( const Tensor& in, Tensor& out ) interface, and any extra parameters should be part of the constructor.
