An undo/redo library with static dispatch and manual command merging.
It uses the [Command Pattern](https://en.wikipedia.org/wiki/Command_pattern) 
where the user modifies a receiver by applying `Command`s on it.

The library has currently two data structures that can be used to modify the receiver:

* A simple `Stack` that pushes and pops commands to modify the receiver.
* A `Record` that can roll the state of the receiver forwards and backwards.
