worked on deck.cpp
finished with deck.cpp, haven't debugged yet
oops, realized i'm still not finished with shuffle. gotta finish that. fixed the Deck() constructor so it compiles though. main() for debug compiling purposes
still working on shuffle in deck.cpp, need to add the end part where the leftover of one side of the cut gets added to the end of the new deck
finished deck.cpp, just need to check if it compiles
