Q: When I get a ButtonDown event on a patch, all I have is the handle
  passed as a paramter to setSelectedHex(). How do I get from the
  handle to the hex coords I need to assign to selectedHexLocation?

A: You could use the screen coordinates of the mouse click and do
complex math, but the following is easier: In board.draw, each time
you draw a hex you get a handle back. Store that handle temporarily
and assign it some user data you want later, like the coordinates on
the board: set(tempHandle, 'UserData', [3 4]). Then later you can get
the coordinates back when you have only the handle by using the get
ccommand.

Q: Is a "player" in a Hex object the same as a "Player" in a Game
object?

A: No. The player in a Hex is just a number, not an Object.

Q: I used EdgeColor in showPath to highlight, and sometimes I cannot
see my new edge color after I call showPath(). Where is it?

A: It may not be on top of the various things in the figure. You can
force it to the top by saying  

uistack(someHandle,'top');

Q: When is the index of a Player set?

A: When the Player is passed in to the Game constructor, i.e. the game
decides which is player one and which is player two.

Q: What does the closeHexGame method do?
