// returns "win", "loss", or "push" based on the result of the bet
// This doesn't have to use the current/market lines
// ex: You can override the "spread" value in oddData on a spread bet and the result will be based off of that spread

  // Unless otherwise mentioned, score represents raw score for the given statEntityID + periodID + statID combo
  // Example 1: statEntityID=LEBRON_JAMES_LA_LAKERS periodID=2q statID=rebounds  =>  score will be Lebron James' 2nd quarter rebounds
  // Then the score will be Lebron James' rebounds in the 2nd quarter
  // Example 2: statEntityID=home periodID=game statID=points => score will be the total points scored by the home team in the game
  // (in the above example note that "points" statID means goals for soccer/hockey, sets for tennis, points for football, etc.)
  // Example 3: statEntityID=all periodID=reg statID=bothTeamsScored => score is 1 if both teams scored in regulation, 0 otherwise

  // Exceptions to the above rule:
  // 1. For "draw" & "not_draw" sideIDs in ml3way bets, score represents the score difference (home - away) between the 2 teams
  // 2. If a game goes into a shootout (ex: soccer, hockey) the shootout winner is awarded 1 goal (statID of "points")
