Please add a clearChange() to cortex

[serle]

Could I suggest that you add a clearChanges() function to Cortex. This would have the side effect of making a ssubsequent call to didChange() function return false again (unless there was infact another cortex change.

The use case would be

onUpdate(updatedData) {
React.render({model: updatedData}) //it can fully utilise the didChange() for render optimisation

  updatedData.clearChanges() //this ensures that subsequent React re-rendering base on prop or  state outside of cortex control can be optimised alongside a properly working cortex.didChange() call which now returns false when it did not change since the last clearChanges()  

}

This is a good idea, but one danger with something like this is you have to guarantee it's only called at the very end of the render loop. I don't think you can simply call it in onUpdate callback because there's no way to be sure react finishes rendering all its components. I'd rather make this an option and hook into react componentDidUpdate to prevent users from improperly calling it.
