Public Methods

Method	Description
BitCount ( ulong bitField ) : int	Fast Bitcounting method (adapted from snippets.org)
CardRank ( int card ) : int	Given a card value, returns it's rank
CardSuit ( int card ) : int	Given a card value, returns it's suit
CompareTo ( object obj ) : int	Used to compare one hand to another. This method allows normal compare functions to work as expected with a hand.
