Function suggestions::provide_suggestions

pub fn provide_suggestions<I, T>(
    target: &str, 
    possible_values: I
) -> Vec<String> where
    T: AsRef<str>,
    I: IntoIterator<Item = T>, 

Suggest strings that are similar to target, but are actually present in the possible_values.

Returns an empty vector vec![] if there is nothing reasonbly similar.

The implementation sorts suggestions based on its internal notion of similarity (from best -> worst).

See also provide_a_suggestion, which only picks a single suggesetion.
