# What is Hailstone?
- Hailstone is a program for testing different functions from the `beetle-collatz` crate
- Run in debug mode for correctness, or in Release mode for

# What the dependencies for
- `beetle-collatz` provides all the functions related to the Collatz Conjecture we need.
- `inquire` provides the Terminal UI
- `rayon` provides multi-threading for multi-core CPUs
- `strum` & `strum-macros` allow for better parsing of user input to enum variants (makes adding and removing options from the Terminal UI easier)
