Non-member lexicographical comparisons

template <typename Key, typename T, typename Compare, typename Allocator>
bool operator<( const concurrent_multimap<Key, T, Compare, Allocator>& lhs,
                const concurrent_multimap<Key, T, Compare, Allocator>& rhs )

Returns: true if lhs is lexicographically less than rhs.
