- Added overloaded ostream<< operator that will allow us to output either a Card or Card*
	eg. cout << cardInstance;
This operator prints out the code, name, cost, and rarity on one line, each separated by a space, no newline at the end

- Added static display function to be passed into generic classes.
	eg. hashTablePtr->printTable(Card::display);
