Movement methods
This is the collection of movement methods within the Checkpoints interface. There are only three movement methods, goBackward, goForward, and goTo.
goBackward
The goBackward method moves the state of the underlying Store back to the previous checkpoint, effectively performing an 'undo' on the Store data.
goForward
The goForward method moves the state of the underlying Store forwards to a future checkpoint, effectively performing an 'redo' on the Store data.
goTo
The goTo method moves the state of the underlying Store backwards or forwards to a specified checkpoint.
