History has been added to the game. There is now a move label describing the latest move. The slider needs to be tied into the history array to allow a view through past plays.
Three card mode also needs to be implemented. Right now the game only matches two cards.
The deal button needs more logic added to allow a reset of the game state.
Read from the segmented control and add to the index to get which game mode we should be in.
Game now has a stored history of what plays were made and it is possible to scroll through this.

Game mode is now selectable, but the match feature is currently
unfinished. Implementing a match-n feature. Where the game will take
each card and compare rank and suit with the rest of the cards. The
match method will return the highest score from this.
Next feature will be adding new back and front images. And if time
permits, changing this to a more iOS7 look.
