• Default class-name is now null for deleted and inserted data, and "change" for change data
• Default tag for deleted data is del
• Default tag for inserted data is ins
• can now customize diff algorithm in DiffRowGenerator.Builder
• fix "equal" lines when lines isn't really equals (when Equalizer return equals on different strings)
• fix imbrication tag bug in lineDiff (when inline is on a multi-line chunk)
• Adds tha ability to skip data

• make Equalizer configurable. (pull #1)

• bugfix: parse method should be public
