Two-Player Pig

Pig is a folk jeopardy dice game with simple rules: Two players race to reach 100 points. Each turn, a player repeatedly rolls a die until either a 1 ("pig") is rolled or the player holds and scores the sum of the rolls (i.e. the turn total). At any time during a player's turn, the player is faced with two decisions:

Problem:  Simulate a single solitaire game of Pig where a player rolls until a 1 ("pig") is rolled, or the turn total is greater than or equal to 20, or the score plus the turn total is greater than or equal to 100.

Note: Be sure to "factor out common code".  There is no reason to have two separate, nearly identical sections of code for each player's turn.
