Function validate_map 

pub fn validate_map<I>(map: &BTreeMap<I, BTreeSet<I>>) -> bool
where
    I: Eq + Hash + Clone + Ord,

Available on crate feature chili only.

Validates a given map.

This algorithm checks if every keys neighbors also contain the specified key. If this is not the case, the map cannot be considered valid. Note that this algorithm does not check if all keys are connected. This means, disjoint sets are allowed.
