Composable undo package

[surajbarkale]

I have published a new package https://github.com/aacapella/swift-composable-undo that implements undo/redo functionality. UndoManager is also supported but not required for the functionality.

Awesome effort @surajbarkale. This looks pretty cool. I haven't used UndoManger much myself, but this seems like something people would appreciate for sure.

Just wanted to echo @iampatbrown's reaction. This definitely looks cool, @surajbarkale! Thanks for sharing 😄

I am using your work the template. So thanks for setting an example. I shall update the docs as I get some time.
