+ * * Depth: The number of levels in the tree, it also defines the maximum number of leaves as 2**depth.
+ * * Zero value: The value that represents an empty leaf. Used to avoid regular zero values to be part of the tree.
+ * * Hashing function: A cryptographic hash function used to produce internal nodes.
+ *
+ * This is a fork of OpenZeppelin's [`MerkleTree`](https://github.com/OpenZeppelin/openzeppelin-contracts/blob/9af280dc4b45ee5bda96ba47ff829b407eaab67e/contracts/utils/structs/MerkleTree.sol)

+ * stored, but can be proven to be part of the tree at a later time if the root is kept. See {MerkleProof}.

+ * * Depth: The number of levels in the tree, it also defines the maximum number of leaves as 2**depth.
+ * * Zero value: The value that represents an empty leaf. Used to avoid regular zero values to be part of the tree.
+ * * Hashing function: A cryptographic hash function used to produce internal nodes.
+ *
+ * This is a fork of OpenZeppelin's [`MerkleTree`](https://github.com/OpenZeppelin/openzeppelin-contracts/blob/9af280dc4b45ee5bda96ba47ff829b407eaab67e/contracts/utils/structs/MerkleTree.sol)
