/** This class implements a temporary or "virtual" parse stack that
 *  replaces the top portion of the actual parse stack (the part that
 *  has been changed by some set of operations) while maintaining its
 *  original contents.  This data structure is used when the parse needs
 *  to "parse ahead" to determine if a given error recovery attempt will
 *  allow the parse to continue far enough to consider it successful.  Once
 *  success or failure of parse ahead is determined the system then
 *  reverts to the original parse stack (which has not actually been
 *  modified).  Since parse ahead does not execute actions, only parse
 *  state is maintained on the virtual stack, not full Symbol objects.
