/**
 * Classes for deriving key triples for wallet addresses.
 *
 * By default, BitGo wallets consist of a triple of bip32 extend keypairs.
 * Every wallet address can be identified by _(chain: number, index: number)_.
 * The key set for a particular address can be obtained by deriving with the path
 * `0/0/${chain}/${index}`. (In rare cases the prefix 0/0 can be different)
 *
 * Since we never use other derivations for utxo address scripts, the classes defined here only
 * allow exactly one level of derivation.
