  1. Instantiate the Delegator smart contract given all of the code hashes and a starting value.
  Make sure the endowment is big enough (if you're using our `substrate-contracts-node` it's `1000000`).
  The Delegator smart contract will take over the work of instantiating the other smart contracts for you.
