Return true if the specified lhs and rhs objects have the same value, and false otherwise. Two unordered_multiset objects have the same value if they have the same number of value elements, and for each value-element that is contained in lhs there is a value-element contained in rhs having the same value, and vice-versa. Note that this method requires that the (template parameter) type KEY be equality-comparable (see {Requirements on KEY}).
