Hangman

This is a terminal implementation of the classic game of hangman, typically played using a pen and paper. A series of unknown letter positions are marked with underscores, and a gallows is drawn. The player must then sequentially guess the letters that make up the unknown word. On each mistake, a body part of a hanged man is drawn on the gallows. If the full man is drawn (7 mistakes in this version), the player loses. If the player guesses all letters in the word, they succeed.
