/**
* A multimap which forwards all its method calls to another multimap. Subclasses should override
* one or more methods to modify the behavior of the backing multimap as desired per the decorator pattern.
*
* {@code default} method warning: This class does not forward calls to {@code
* default} methods. Instead, it inherits their default implementations. When those implementations
* invoke methods, they invoke methods on the {@code ForwardingMultimap}.
