A card is represented by an object with properties 's' and 'v', where 's' describes the suit (s = spade, h = heart, c = club, d = diamond) and 'v' describes the value (1 = ace, 13 = king).

bestHand(cards) - returns a results object with the best 5-card hand (sorted), a string describing the hand, an integer hand value (0 = high card, 8 = straight flush)

var ranker = require('hand-ranker');
 
var cards = [
  { s: 's', v: 10 },
  { s: 'c', v: 1 },
  { s: 's', v: 13 },
  { s: 's', v: 1 },

  { s: 's', v: 12 },
