class Stack:
"""A generic stack of cards.
This is used as a base class for all other stacks (e.g. the deck,
the suit stacks, and the row stacks).
Public methods:
add(card) -- add a card to the stack
delete(card) -- delete a card from the stack
showtop() -- show the top card (if any) face up
deal() -- delete and return the top card, or None if empty
Method that subclasses may override:
position(card) -- move the card to its proper (x, y) position
The default position() method places all cards at the stack's
own (x, y) position.
userclickhandler(), userdoubleclickhandler() -- called to do
subclass specific things on single and double clicks
The default user (single) click handler shows the top card
face up. The default user double click handler calls the user
single click handler.
usermovehandler(cards) -- called to complete a subpile move
The default user move handler moves all moved cards back to
their original position (by calling the position() method).
Private methods:
clickhandler(event), doubleclickhandler(event),
motionhandler(event), releasehandler(event) -- event handlers
The default event handlers turn the top card of the stack with
its face up on a (single or double) click, and also support
moving a subpile around.
startmoving(event) -- begin a move operation
finishmoving() -- finish a move operation
