Verifies that the actual is sorted into ascending order according to the natural ordering of its elements.
Empty arrays are considered sorted.

@param description contains the information about the assertion.
@param actual the given array.
@throws AssertionError if the {@code actual} is {@code null}.
Verifies that the actual is sorted into ascending order according to the natural ordering of its elements . Empty arrays are considered sorted .
