This project is a Pokemon battle simulator demonstrating OOP principles. There are two base classes with several children as shown in the following UML diagram:

The current implementation is incomplete. You should extend it to include the following:

1. Add a GrassAttack class that is a child of Attack.
2. Add VineWhip, a GrassAttack that deals 5 damage.
3. Add Bulbasaur, a GrassPokemon with 20 HP that uses VineWhip.
4. Add Tackle, an Attack that deals 4 damage.
5. Add Rattata, a Pokemon with 16 HP that uses Tackle.
6. Adjust FireAttack to apply double damage to GrassPokemon.
7. Adjust GrassAttack to apply double damage to WaterPokemon.
8. Add Charizard, a FirePokemon with 150 HP that uses a new FireAttack called FlameThrower that deals 60 HP of damage.
9. Add Venusaur, a GrassPokemon with 225 HP that uses a new GrassAttack called RazorLeaf that deals 95 HP of damage.

Once these features have been added, all included doctests should pass. These can be executed by running:

python3 -m doctest battle.py

or simply:

make test
