Galliwasp 1.0.4: June 22, 2012
- Added detailed error messages for scanning and parsing. Debugging invalid
  programs should now be much easier.

Galliwasp 1.0.3: June 1, 2012
- Major improvements to compiler speed for programs with a lot of headless 
  rules.

Galliwasp 1.0.2: May 27, 2012
- Fixed a bug where literals could succeed by calling themselves with no
  intervening negation, if backtracking occurred after they had previously
  succeeded.
- Fixed a bug where a valid recursive call could fail when it should have
  succeeded.

Galliwasp 1.0.1: May 7, 2012
- Fixed a bug which allowed all clauses of an NMR sub-check to be disabled
  without failure occuring, which could result in invalid answer sets being
  returned.

- Initial release.
