fun verify(merkleRootHash: SecureHash, hashesToCheck: List<SecureHash>): Boolean
Function to verify a PartialMerkleTree against an input Merkle root and a list of leaves. The tree should only contain the leaves defined in hashesToCheck.
merkleRootHash - Hash that should be checked for equality with root calculated from this partial tree.
hashesToCheck - List of included leaves hashes that should be found in this partial tree.
