Crate undo

An undo-redo library with dynamic dispatch and automatic command merging. It uses the command pattern where the user modifies a receiver by applying commands on it.

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

• A stack that can push and pop commands to modify the receiver.
• A record that can roll the state of the receiver forwards and backwards.
