Me and Taylor Gerring (Hive wallet) coded this example wallet in 2 days
in pure Python. It uses python-obelisk and is meant to be be an example
for other coders to understand how wallets work. We'll work slowly on
more tutorials and docs.

It uses kivy and has no dependencies, so can be used on the mobile phone.

This is great for wallet developers and GUI designers who want to create
their own skin or special wallet with specific features. For example:
wallets for traders, branded wallets for businesses and specific payment
applications that use wallet functionality.
