Completed the day 5 requirements; updateUI was updated, updated the cardmatchinggame model, updated the story board, etc.
I have the GUI setup like I want it to, I think. Now to start adding functionality.
The result text is now correctly showing matches, mismatches, and the associated point values for each.  I have that being stored in an array, and the next step is to allow the slider to display the contents of the array.
I have the history slider working now, and hopefully without crashing the app either.  :) On to the final piece, which is doing the logic for a 2 or 3 card matching game depending on what the user chooses.
The logic for 3 card -- or any number of card matching, really -- is working now.  All the requirements for the project have been met, in addition to the extra credit requirement.
Correctly made it so that only certain number of cards are face up at a time.  Also added alpha transparency to the history label as you go back in time.
Removed the two weird warnings that were appearing on the launch screen.  Now no warnings or errors.
Created a basic readme file
Updated the readme a little to make it easier to read.
The tab bar is in, in addition to a complete copy of the storyboard for the set game and all the outlets are still connected.  Now to start modifying the controller behind it.
For the moment, the SetCard model appears to be somewhat ready.  I now need to be able to display each card and draw it out using attributed strings in the view, somehow.
The set game is now showing card faces correctly.  Next I need to make it so it's showing the actual shapes, colors, etc.
The set cards are now displaying the symbols.  The last thing to do is to use attributed strings to get the shading and colors correct.
The color, shapes, and fills are working on the set cards.  I noticed that there is a bug if a card is flipped and then flipped again; need to change that in the flipcard checker.  Also, need to update the history tracker to take attributed strings.
Fixed a bug that would incorrectly handle if you flipped a card and then decided to flip to back down again.  Now the game recognizes that the card is no longer playable and face up, and it won't get confused.
I think I have the attributed string result label and attributed string result history working now.
Fixed an off-by-one error on the history slider.  Now it correctly shows the history of the latest flip.
