Class org.as2lib.regexp.node.GroupHead

Description

GroupHead saves the location where the group begins in the locals and restores them when the match is done. The matchRef is used when a reference to this group is accessed later in the expression. The locals will have a negative value in them to indicate that we do not want to unset the group if the reference doesn't match.
