Fixed errors for the test_grid tests. I put an extra check on the arguments that are passed into run_system where i catch the ones ending with %d

Updated code to handle with pycapsules. Assignment of memory is only done within the multiprocessing process/thread, otherwise we cant  use multiprocessing

small changes: less output and some extra infp. also checking the last line of a output to see if the SYSTEM_ERROR is in there

removed some functions for the persistent data cause that wasnt persistent when passed through threads
