## Getting started
Construct tree, generate proof
```rust
use merkeltreerust::merkeltree::MerkelTree;
use merkeltreerust::option::Options;
use merkeltreerust::buffer::Buffer;
use merkeltreerust::error::MerkelTreeError;
use tiny_keccak::{Hasher, Keccak};
let whitelist_address: Vec = vec![
"0x6dC0c0be4c8B2dFE750156dc7d59FaABFb5B923D".parse::()?,
"0xa8d17cc9caf29af964d19267ddeb4dff122697b0".parse::()?
];
let options = Options { duplicate_odd: false, sort_pairs: true, sort_leaves: true, sort: true, hash_leaves: true };
let hash_fn = |buf: &[u8]| {
let mut k256 = Keccak::v256();
let mut result = [0; 32];
k256.update(buf);
k256.finalize(&mut result);
result.to_vec()
};
let merkle_tree = MerkelTree::new(whitelist_address, hash_fn, options);
let root = merkle_tree.get_root()?.to_hex();
let leaf = "0x6dC0c0be4c8B2dFE750156dc7d59FaABFb5B923D";
let proof = merkle_tree.get_hex_proof(leaf.parse::()?)?;
println!("root: {:?}", root);
println!("leaf: {:?}", leaf);
println!("proof: {:?}", proof);
```
Output:
```bash
root:0xdb44a1f32851683f64d15a563ecd3686b67de2075821b6196dbaf7d25604592f
