GENERATORS: Functions are no longer inlined

Functions declared inline should be an exception. Hence they
require special attention (for writing/maintaining/linking),
which basically means they are a burden on the developer.
Inline functions are no longer used in this project - we now
rely on smart compilers and global optimization. If it does not
work, we will change it...but in the optimization stage.

TESTS: Fixed a "multiply defined" linker issue

This was due to an inline function not declared static.
We use inlmine in this only case because tests.h should
be kept as a header only, for the sake of simplicity.
