Suggestion for new features

[alanyee]

1. Add -o for output file option. > or >> somewhat suffices but there is a backspace character for ^C
2. Add -t for threading in order to ping more than one destination host at a time
3. Add an option to remove exit statistics. Sometimes the exit statistics is not needed
4. Add option to toggle a different file output i.e. csv, tsv
5. Add an API so that we can send output to something i.e. database or webserver
