Card Class and Card List

Started a very basic card object. Not entirely sure of the best way to
define a card - we'll have to brainstorm some ideas. I also added a
spreadsheet that contains the name, type, value, and count of each card.
Counts still need to be added for most cards (non-property cards). This
spreadsheet will be read in and used to create the deck.
Deck Class

Started basic deck class. Creates an object of an array of cards.
Includes a shuffling function I found online.
