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 pushes and pops commands to modify the receiver.
• A Record that can roll the state of the receiver forwards and backwards.

It also has a structure called Group that can be used to group multiple stacks or records together.
