Command-line implementation of the nim-like "100 game." Two players start with a shared total of zero. On each turn, a player adds a number from 1 to 10 to the total. Whichever player reaches 100 first wins.
Currently players can enter non-numeric types (which instantly crash the program), numbers smaller than 1 or bigger than 10, and decimals. Validation that ensures players enter integers between 1 and 10 is necessary.
