Compare the contents of two queue.     (1-2) Checks if the contents of lhs and rhs are equal, that is, whether each element in lhs compares equals with the element in rhs at the same position.     (3-6) Compares the contents of lhs and rhs lexicographically. The comparaison is performed by a function equivalent to std::lexicographical_compare.

T must meet the requirements of EqualityComparable in order to use overload (1-2).
T must meet the requirements of LessThanComparable in order to use overload (3-6).

(1) true if the contents of the containers are equal, false otherwise.
(2) true if the contents of the containers are not equal, false otherwise.
(3) true if the contents of the lhs are lexicographically less than the contents of rhs, false otherwise.
(4) true if the contents of the lhs are lexicographically less than or equal the contents of rhs, false otherwise.
(5) true if the contents of the lhs are lexicographically greater than the contents of rhs, false otherwise.
(6) true if the contents of the lhs are lexicographically greater than or equal the contents of rhs, false otherwise.

Constant.
