changed the examples to work again, modified the run_system python function to handle stuff correctly, in a cleaner fashion

updated grid code to be more clean, and have dedicated setup and cleanup functionalities. hopefully code will stay cleaner

added testing and the cleaning up of the custom library. this isnt done yet, and ive hit on some sissues

created file that will contain examples of logging lines/custom logging snippets for people to use as an inspiration

Tried to fully package the core api but that seems like a very difficult endeavour, as passing the shared library via package_data is not enough. it complains about missing symbols, meaning that the other shared/linked stuff is not working anymore. it only works good if things are now loaded by adding this package to the PYTHONPATH atm. will do it later with pip, but thats gonna be some more work
