TODO LIST:

  - Update README
  - Write functions for moving wumpus, player movement, player shooting, parsing player commands.
  - Write a function 'get highest tunnel index' for use in the 'check for pits/bats/wumpus' functions.
  - Double-check per-file TODOs for critical tasks.
  - Double-check #includes for all subroutines.
  - Re-order subroutines in all files for readability.
