The Quest

You are to register for this Token Game with your name. Make this call with your already whitelisted address. This deploys your own Vault Token Contract (Locate your own contract). To win:

1. Drain the Token contract of all VaultTokens (isComplete()).
2. Make sure the Token contract has no ETH (drained()).

STEPS TO COMPLETE CHALLENGE

STEP 1: Register your name on the TokenFactoryGame using the register()
