Object	getChangeTag() Gets a tag for this change, so that two changes, both making modifications to the same field, can replace each other, as they must be mutually exclusive
V	getValue() Gets the value that will be set on the model in modify(M).
boolean	isCurrentValue(M model) Checks to see if the given model already has the change
void	modify(M model) Make the change recorded here to the given model
