//| 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. |
