Determines whether two iterators contain equal elements in the same order. More specifically,
this method returns {@code true} if {@code iterator1} and {@code iterator2} contain the same
number of elements and every element of {@code iterator1} is equal to the corresponding element
of {@code iterator2}.

<p>Note that this will modify the supplied iterators, since they will have been advanced some
number of elements forward.
