### Baby Nim, aka Empty the Piles

Write a program that starts with three "piles" of 3 counters each. Let
the player choose piles and remove counters until all the piles are
empty.

- Start by placing counters (coins or toothpicks or something) into 3 piles.
- The player picks a pile, then removes one or more counters from that pile.
(It's okay to take the whole pile.)
- The player picks a new pile, then removes one or more counters from that pile.
(It's okay to pick the same pile as before.)
- Once all piles are empty, the game stops.

You do not need to check for errors like a wrong pile name, or if someone
tries to take more counters from the pile than the pile has.

## Sample Output

Here is an example game, with starting piles of 3 counters.

A: 3 B: 3 C: 3
Choose a pile: `A`
How many to remove from pile `A`: `2`
A: 1 B: 3 C: 3
Choose a pile: `C`
How many to remove from pile `C`: `3`
A: 1 B: 3 C: 0
Choose a pile: `B`
How many to remove from pile `B`: `1`
A: 1 B: 2 C: 0
Choose a pile: `A`
How many to remove from pile `A`: `1`
A: 0 B: 2 C: 0
Choose a pile: `B`
How many to remove from pile `B`: `1`
A: 0 B: 1 C: 0
Choose a pile: `C`
How many to remove from pile `C`: `2`
A: 0 B: 1 C: -2
Choose a pile: `B`
How many to remove from pile `B`: `1`
A: 0 B: 0 C: -2
All piles are empty. Good job!
