The below examples are implemented as integration tests:

• Import a BIP32 testnet xpriv and export to WIF
• Export a BIP32 xpriv, then import it
• Export a BIP32 xpub
• Create a BIP32, bitcoin, account 0, external address
• Create a BIP44, bitcoin, account 0, external address
• Use BIP39 to generate BIP32 addresses
