Return a Merkle proof from the key/value pair back to the application hash. Return a Merkle proof from the key/value pair back to the application hash.<br/>
*Please note* The current implementation of go-merkle doesn't support querying proofs from past blocks, so for the present moment, any height other than 0 will return an error. Hopefully this will be improved soon(ish)
