Works with Noir > 0.7.1.

## Usage

In your `Nargo.toml` file, add the following dependency:

```toml

[dependencies]

noir_merkleroot = { tag = "v0.1.1", git = "https://github.com/tomoima525/noir-merkle-root" }

use dep::std;

fn main(

    root: Field,

    leaf: Field,

    path_indices: [Field; 8],

    siblings: [Field; 8],

) {

    // generate merkle root

    let new_root = noir_merkleroot::compute_merkle_root(leaf, path_indices, siblings);

    assert(new_root == root);

}

```
