By request of AoC creator, I haven't included the input files (e.g. src/input/day01.txt). Log into the Advent of Code site and save the inputs there to the src/input/ folder.

Then to run: cargo run.

To run in super-fast prod mode: cargo run --release.

To run with debug logs enabled: RUST_LOG=debug cargo run.

To run the tests against included test input files: RUST_LOG=debug cargo test -- --no-capture.
