ChangeHistory for ConboJS 4

The ChangeHistory class is a simple object state history manager for ConboJS that enables you to navigate back and forward through the history of every property change made to any object that extends the EventDispatcher class, including Hash, Application and View, effectively making it possible to return to any of an object's past states.

The ChangeHistory class can be imported as an AMD, CommonJS or global module.

• back() moves back 1 step into history
• forward() moved forward 1 step in hisyory
• go(n) moves n steps backwards or forwards in history
• currentIndex is the current place in history
• beforeFirst indicates whether you are at a point in history before any changes were made
• atLast indicates that you are at the end of history

Initialising ChangeHistory for an object couldn't be easier:

var history = new ChangeHistory(obj);
