print poker hands for each player

@jsteiner @gabebw
What about using a hash here?

```ruby
# at the top of the class
NAMED_RANKS = {
  1 => "A",
  10 => "T",
  11 => "J",
  12 => "Q",
  13 => "K"
}

def poker_rank
  if NAMED_RANKS.key?(@num)
    NAMED_RANKS[@num]
  else
    @num
  end
end
```
