    This is a main method that should be usable for almost all purposes and
    reduces executing coala to one function call.

    :param log_printer:             A LogPrinter object to use for logging.
    :param print_results:           A callback that takes a LogPrinter, a
                                    section, a list of results to be printed,
                                    the file dict and the mutable file diff
                                    dict.
    :param acquire_settings:        The method to use for requesting settings.
                                    It will get a parameter which is a
                                    dictionary with the settings name as key

                                    setting in all following indexes.
    :param print_section_beginning: A callback that will be called with a
                                    section name string whenever analysis of a
                                    new section is started.
    :param nothing_done:            A callback that will be called with only a
                                    log printer that shall indicate that
                                    nothing was done.

                                    default; this is overridable via any
