Handles one Backgammon match.

• Match(uint matchLength, const char* opponentName = 0)

Match to matchLength.
• Match(std::istream& saved)

Load saved match from saved.
• enum Side

Backgammon sides are conventionally known as `X' and `O'.

• class Action

• const Action* next(void)

Next action to be processed by UI.


---

Calls made by the UI code when user makes an action Typically those return false if action is not appropriate (i.e. out of turn). Typically this indicates a bug in the calling code, and I suggest asserting them there, especially during development.
