fastercsv gem

Gem details

FasterCSV is intended as a replacement to Ruby's standard CSV library. It was designed to address concerns users of that library had and it has three primary goals:

1. Be significantly faster than CSV while remaining a pure Ruby library.
2. Use a smaller and easier to maintain code base. (FasterCSV is larger now, but considerably richer in features. The parsing core remains quite small.)
3. Improve on the CSV interface.
