-//| Description: |
-//| The base class for holding piles of playing cards. |
-//| This is the basic building block for card games. A pile |
-//| has a position on the screen and an offset for each |
-//| card placed on it e.g. a pack has no offset, but the |
-//| discard pile may be fanned out across the screen. |
-//| |
-//| The pile knows how to draw itself, though this may be |
-//| overridden if the default layout needs to be changed. |
-//| One or more cards can be removed from the top of a pile, |
-//| and single cards can be added to the top of a pile. |
-//| Functions are provided which redraw the screen when |
-//| cards are added or removed. |
-//| |
-//| Cards know which way up they are and how to draw |
-//| themselves. Piles are lists of cards. Piles know which |
-//| cards they contain and where they are to be drawn. |
