Get a reference to the value associated with a key. # Arguments `key` - The key to look up # Returns A reference to the value if the key exists, `None` otherwise. # Examples ``` use bplustree::BPlusTreeMap; let mut tree = BPlusTreeMap::new(16).unwrap(); tree.insert(1, "one"); assert_eq!(tree.get(&1), Some(&"one")); assert_eq!(tree.get(&2), None); ```

    /// ```
    pub fn get(&self, key: &K) -> Option<&V> {
