removed overwrite_existing_exportfilename_content (won't use it myself, wouldn't make sense for others to not overwrite something they re-calculated)

switched from args to config (args still work)
renamed exportfilename to lookahead_analysis_exportfilename so if users decide to put something into it then it won't compete with other configurations
