Pass arrays to shared libraries from python using C types

This example implements a simple shared library in C.

This library called libfifthy exposes a function called add_fifthy which takes an array of integers and modify it in place by adding 50 to all elements.

Then there's some code in python which builds an array and invokes the add_fifthy from the shared library and reads the altered array values.
