  <p>Multiplicity is respected. For example, an object duplicated exactly 3 times in the
  parameters asserts that the object must likewise be duplicated exactly 3 times in the subject.
  
  <p>To also test that the contents appear in the given order, make a call to {@code inOrder()}
  on the object returned by this method.
