Class BIP32

BIP32 represents a BIP32-compatible hierarchical deterministic wallet (or 'HD Wallet').

BIP32 wallets are crypto-wallets which can be shared partially or entirely with different systems, each with or without the ability to access coins/data. This implementation is based on a derivation (and extraction for modularity) of the HDWallet/HDNode written and tested by bitcoinjs-lib contributors since 2014.
