Can Team::get_pets() return std::vector<Pet const*> ???

Questions

Does Crab copy less than its own life (i.e. 3) ? [Here: no]
Does Dodo gives to dead pets ? [Here: no]
Cricket + 2xHedgehog -> H1 kills C and H2 -> does H2 kill ZC or ZC spawns after every thing ? [Here: H2 kills ZC]
[Blowfish 3/5] | [Fish 2/3 - Snake 6/6] -> Does the blowfish fires ? How many times ? What about when it has 20 hp ?

ToDo

Env
- Compute mask
Agents
- Agent::save_action() -> saves pair (state, action) in buffer
- Agent::write_to_file() -> saves this buffer to a file for debug purposes
RandomAgent
- Option to be totally random or categorically random
Memory leak check
Rule-based Agent

Order

Start of battle:
- Sort by attack, resolve
- All abilities triggers (even if dead) BUT if dead and change stats (e.g. butterfly), still dies
