moving to single shell script with multiple input args, tman.sh. got working through input checking, moving to using printf to format output to timesheet files
move everything to local hidden folder. got the first pass working, prints out summary files, daily log files, etc using printf. need to check a few more cases, e.g., if day already exists in summary file. also probably add some extra options to recover from deleting log files or forgetting to logout or adding notes after the fact. but this one works alright!
