cargo fmt pre-commit hook

To ensure every contributor uses the same code style, make sure you run cargo fmt before committing. You can force yourself to do this by creating a git pre-commit hook like the following:

#!/bin/sh
if ! cargo +nightly fmt -- --check >/dev/null; then
    echo "There are some code style issues. Run 'cargo fmt' to fix it."
    exit 1
fi

exit 0

Place this script in .git/hooks/pre-commit and make sure it's executable by running chmod +x .git/hooks/pre-commit.
