Browse Source 
- Changed to the MIT license.

- Added offset and limit options.

- Added SQL-like conditions for quickly
  filtering out entries. Documentation on the
  condition syntax is forthcoming.

- Small parsing modification to comply
  with some recent changes to the specifications
  outlined on Wikipedia's Comma-separated values
  article.

- Minor changes and optimizations, and a few
  spelling corrections. Oops :)
