Player handler package

This package defines a player data structure, collections of players,
and different interactions you can have with them:
- Extracting attributes (destructors)
- Checking if they're bankrupt or can bet
- Modifying a collection to adjust the balance of any one
  player (including errors in case that isn't possible)
