Update Readme.md

In Readme, width for the gif size was too small to see the app demo so the width was increased from 200 to 400.

Updated the Readme to include the new features added to the app and updated gif file. In addition, the multiple choice answers are randomized.

Added app icon, splash screen, button icons, and animation to the flashcard and multiple choice buttons.

Changed the Readme file to include the new features of the app such as saving and deleting flashcards.

Finished implementing the multiple choice button title updates when user creates new flashcards and edit existing ones. Also, implementation to save multiple choice answers in disk.

Implemented another edge case of the deletion of the flashcard, i.e. when user wants to delete the only card on the set it should not be allowed otherwise it will crash the app.

Implemented a delete/cancel flashcard button.

Implemented the set of flashcards, browsing through flashcards, savings to disk, and reading from disk.

Merge remote-tracking branch 'refs/remotes/origin/master'

Saving current status before change. Going to change the tap gesture recognition that enables flipping the flashcard around.

Update Readme.md

Included the buttons to reappear when the user edits the flashcards, otherwise the extra buttons wouldn't show again if they were clicked prior to editing the flashcard. Updated the gif to show the new changes made to the app, i.e. the optionals. Currently working on how to scramble or randomize the answer because at this point, the second multiple choice contains the correct answer.

Make the multiple choice buttons reappear when they are hidden after user goes to edit mode.

Finished the optionals parts of the lab. Trying to implement randomized answers to avoid predictability in multiple choices.
