updated grid code to handle a shared result dictionary, took some effort but it works now. requires some tricks here and there tho

Changed the api code: removed all the functions that did a slightly different thing. put them into 1 function that has several options. Moreover, cleaned up code, test functions, and other functions throughout code

added general run_system api binding, which will eventually replace the individual ones. this function runs a system, and depending on the input it will use a custom logging, a preloaded store, write log to file etc. I think it will be better to just write some if statements in a single function, and not have too many repeating code

Rewrote argument handling of population class, added export functions. Added python-c-bindings to return store and other small changes

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
