/**

 * @dev Basic functionality for a MerkleTree that will be used as a "Claimlist"
 *
 * "Claimlist" - an approach for validating callers that is backed by a Merkle Tree.
 * Cheap to set the master claim, not that expensive to check the claim. Requires
 * off-chain generation of the Merkle Tree.
 *
 * This library allows you to declare a member variable like:
 * MerkleClaimList.Root private _claimRoot;
 *
 * The benefit of packaging this as a library, is that if you need multiple merkle trees in your
 * contract, you can declare multiple member variables using this library, and use them in similar fashion.
 *
 * see also: NFTC Labs' MerkleLeaves.sol, which is a companion abstract contract which contains helper
 * methods for generating leaves for the Merkle Tree.
