Required Methods

fn insert_into_nested(&mut self, outer_key: K, inner_key: K2, inner_value: V)

For use with a hashmap within a hashmap, takes an outer and inner key, and an inner value

1. if the outer key exists with and inner hashmap the key-value pair is inserted to the existing hashmap.
2. a new inner hashmap is created with the key-value pair if the outer key does not exist.
