Updated poll_game so that it's now returning all information that should be needed to format a game page for each player or for a spectator.
Changed functionality of _initialize_round to reflect earlier changes in the Player class.
Poker functionality should now be complete, minus checking validity of moves made and stuff to do with cards.
Implemented _get_previous_player function.
Fixed a couple typos in the player_test file. These tests are still sufficient; it's the game that's going to be a real nightmare to test.
Began implementing tests for overhauled game class. Tests for _get_next_player and _get_previous_player are written and are passing.
Added _get_previous_active_player and _get__next_active_player and added IndexError exception raising to _get_prvious_player and _get_next_player.
Removed old commented out functions and fixed a typo.
Modified player's fold function to return true when the player folds. Added docstrings to all player functions.
Removed _next_player_turn from the game, as it has been replaced by the more general-purpose _get_next_active_player. Began changing implementations to use _get_previous_active_player and _get_next_active_player where appropriate.
Adding clarifying comments and expanded docstrings. No major changes to code.
