Verifies that the given <code>{@link Collection}</code> contains the given sequence of objects, without any other
objects between them.

@param description contains information about the assertion.
@param actual      the given {@code Collection}.
@param sequence    the sequence of objects to look for.
@throws AssertionError           if the given {@code Collection} is {@code null}.
@throws NullPointerException     if the given sequence is {@code null}.
@throws IllegalArgumentException if the given sequence is empty.
@throws AssertionError           if the given {@code Collection} does not contain the given sequence of objects.
