public interface Float2IntMap extends Float2IntFunction, Map<Float,Integer>
Map; provides some additional methods that use polymorphism to avoid (un)boxing, and handling of a default return value.
Besides extending the corresponding type-specific function, this interface strengthens Map.entrySet(),
keySet() and values(). Moreover, a number of methods, such as size(), defaultReturnValue(), etc., are un-defaulted
as their function default do not make sense for a map.
Maps returning entry sets of type Float2IntMap.FastEntrySet support also fast iteration.
A submap or subset may or may not have an independent default return value (which however must be initialized to the default return value of the originator).

This method is necessary because there is no inheritance along
type parameters: it is thus impossible to strengthen Map.entrySet()
so that it returns an ObjectSet
of type-specific entries (the latter makes it possible to
access keys and values with type-specific methods).
