The command line to run a solution is:

cargo run --example=<day>-<part>

Where <day> is the 2-digit day and <part> is 1 or 2. For example, the command line to run the solution for day 14 part 2 is:

cargo run --example=14-2

The command line to test a solution is:

cargo test --example=14-2

The test.sh script can be used to check formatting, linting, and that all solutions still pass their test.
