==========C++ Multimaps==========

C++ Multimaps are like [[stl/map/|maps]], in that they are sorted
associative containers, but differ from maps in that they allow
duplicate keys.

|[[multimap_constructors|Constructors]]|default methods to allocate, copy, and deallocate multimaps|
|[[multimap_operators|Operators]]|assign and compare multimaps|
|[[begin]]|returns an iterator to the beginning of the multimap|
|[[clear]]|removes all elements from the multimap|
|[[count]]|returns the number of elements matching a certain key|
|[[empty]]|true if the multimap has no elements|
|[[end]]|returns an iterator just past the last element of a multimap|
|[[equal_range]]|returns iterators to the first and just past the last elements matching a specific key|
|[[erase]]|removes elements from a multimap|
|[[find]]|returns an iterator to specific elements|
|[[insert]]|inserts items into a multimap|
|[[key_comp]]|returns the function that compares keys|
|[[lower_bound]]|returns an iterator to the first element greater than or equal to a certain value|
|[[max_size]]|returns the maximum number of elements that the multimap can hold|
|[[rbegin]]|returns a reverse_iterator to the end of the multimap|
|[[rend]]|returns a reverse_iterator to the beginning of the multimap|
|[[size]]|returns the number of items in the multimap|
|[[swap]]|swap the contents of this multimap with another|
|[[upper_bound]]|returns an iterator to the first element greater than a certain value|
|[[value_comp]]|returns the function that compares values|
