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..

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

fixing errors: hdf5 file creation when there are no settings. and the setting export if there is a functio in it

added function to parse arguments via commandline, added parsing of version history and and the loading of the generated grid function

 updated help all super function to combine the results of detailed_help to the already present results

added a help all super function that calls help_all first, and then loops over the parametr names to get more information

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

created tet directory with start of test functions. also fixed small bugs and finished the help function

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
