BurntSushi's 2018 Advent of Code solutions

I chose to write this year's solutions in Rust. I don't have any particularly ambitious goals, but I am trying to write the solutions using idiomatic code. In particular, it should not be possible for any input to cause one of the solutions to panic.

I have not spent any time benchmarking the code.

To run a solution, cd into its directory and invoke the program with Cargo:

$ cd aoc01
$ cargo run --release < input/input.txt

If you have questions about the code, please open an issue and ask away! Beginner questions are very much welcome.
