o Moving the generation logic to Python, embedding a Python interpreter with the help of pybind11.

o Adding install configuration to CMake to make it easier to reuse the project later on.
o Splitting out the examples into its own project to make it easier to test the whole installation setup and python/template loading.
o Trying to reorganize the code a bit, not very much better yet.
