moved around functions, fixed the super-help function, changed some of the tests for persistent_data

Processed alot of what pylint suggested. Might change the naming conventions rules tho, the short parameter names are an issue, but lets not get too strict..

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

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

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