        `description` - The description to be built or appended to.

    - #### everyItem

          public static <U> Matcher<java.lang.Iterable<U>> everyItem(Matcher<U> itemMatcher)

      Creates a matcher for `Iterable`s that only matches when a single pass over the examined `Iterable` yields items that are all matched by the specified `itemMatcher`.

      For example:

          assertThat(Arrays.asList("bar", "baz"), everyItem(startsWith("ba")))

      Parameters:
        `itemMatcher` - the matcher to apply to every item provided by the examined `Iterable`
