How to use

Compare two hands by using:

    var player1 = '2s 3d 4h 5s 6d',
        player2 = 'Ts Js Qs Kd As',
        result = poker.compareTwoHands(player1, player2);

Both parameters are strings with cards separeted by spaces. It returns a number greater than 0 if first parameter has a better hand than second parameter. If there is a tie, it returns 0. A number lower than 0 is returned when second parameter has the best hand. Less than 5 cards are not allowed.

Get random hands using the RandomHandGenerator:

    var randomHandGenerator = poker.createRandomHandGenerator(Math.random);

    randomHandGenerator.getRoyalFlush();

RandomHandGenerator must be created with a random numbers generator (between 0 and 1), such as Math.random. By using its methods, it will return a string with a hand representation.
