- Added license information and updated author email
- Fixed a bug to allow fuzzy matching to work when you specify a
  start timestamp that comes before the first packet's timestamp
- Output of -d option to be more mallable (and useful) using shell tools
- bugfix: extraction code had faulty logic that could end up skipping
  packets that should have been extracted. See
  https://github.com/mschiffm/cppip/issues/2 for more information.
- style: return values doen't need enclosing parens
