Fish!

## Description

fish is the classic card game of ‘Go Fish’. In this game, each player has a
set of cards, and the objective is to empty your hand while collecting more
‘books’ of four cards with matching face values than your opponent. Each play,
you must ask your opponent if they have the same card as one in your hand. If
yet, they must give you all of those cards that they own. If not, you must ‘go
fish’ to find the card in the ‘pool’ of cards that are not in either hand, and
then add it to yours.

This is a simple terminal implementation of the game, where you enter the
number or letter of the card to ask for. The computer has two difficulty
settings; the harder setting is requested by pressing the ‘p’ key.
