Summary
Implements a new
print_proof
functionality that combines cryptographic proof generation with visual tree representation, enhancing the demo and debugging capabilities of the Prolly Tree.Problem Solved
Previously, users could only see proof data as raw hash arrays. This feature provides an intuitive visual way to understand how cryptographic proofs work by highlighting the exact path through the tree structure.
