This is really great! Still reviewing, but one comment is that for both examples, can we create an object called Credits which holds the functions within them (and probably an account as well)?

A few nits, but overall this is not just understanding the assignment but going beyond and adding to the curriculum. This is GREAT. Thanks for the quick and hard work.

Generally code convention in Provable is to use periods in docs and code comments outside of headers. Add them to the text in this doc (minus the headers)

Motivation
This PR adds Node.js and React create-leo-app templates that build execution transactions for all 6 functions (
transfer_public,transfer_public_to_private,transfer_private,transfer_private_to_public,join,split), giving developers a working reference for each transfer and record operation type.Test Plan
