BIP32 Hierarchical Deterministic wallet functions - extends bitsv
This project is still in alpha. Expect lots to change - pin your versions if you are using this code!
I will post a road map here in due course.
- I essentially want to have the "leaves of the BIP32 tree" inheriting all of the functionality of a bitsv.PrivateKey to make building prototype applications in Python a breeze.
- Create master node.

>>> # First, lets use the xprv master node (from above) to get the xpub!
