  These procedures use co-expressions to perform operations on
  integer sequences.

	Compl{e}	   produces the integers not in e

	Delta{e, i}	   produces the difference of values in e by
			   i places	  

	Selfrepl{e, j}	   produces i * j copies of i, where i is from
			   e1

	Sumlimit{e, i, j}  produces values of e until their sum exceeds
			   i.  Values less than j are discarded.
