TIO

Demonstrates creating a Toy IO effect system (TIO) from ground up. The architecture and API loosely follows ZIO, but for simplicitly omits typed errors and environment.

You can follow the progression of building up TIO using tags:

1. Creating and combining effects
2. Failing and Recovering from Errors
3. Asynchrony with Callbacks
4. Queuing work
5. Concurrency with Fibers
