 A modifiable, associative collection. Map elements are key-value pairs. Looking up a key to retrieve its associated value, and iterating through all key-value pairs, are both supported.
 
-`Map` and `MapView` are templated on `<K, V, C = std::less<K>>`; therefore, you can customize the comparator.  Additionally, `Vector` and `VectorView` are templated on `<T, E = std::equal_to<T>>` so that you can customize the behavior of `IndexOf()`. This is important mostly for `Vector` and `VectorView` of value structs. For example, to create a `Vector<Windows::Foundation::DateTime>`, you must provide a custom comparator because DateTime does not overload the `==` operator.
