Interfacing with Native code from Python

-- [black] [text-color=white] [font=Sans 40px] [shading-color=black] [shading-opacity=0.66]
Why

 ✔ speeding up hot loops	
 ✔ interfacing with native libraries
 ✔ improving performance in multi-threaded applications
 ✔ interfacing with other computational environments
 ✔ enjoying segfaults
