added debug mode that prints out some stuff of the memory adresses, cleaned up the binding functions and added free store function. next up: fix the grid stuff to handle the ensembles

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
