** Module: Case_Item
** Description: This module implements the Case_Item abstraction. A
** case item represents a single branch in a case statement; it
** thus consists of a list of labels and a statement to execute
** when one of the labels matches the selector.
** Constants:
** CASE_ITEM_NULL - the null item
