;
;
; PURPOSE:
;	To define the structure of a smei operator.

;
;
; ELEMENTS:
; 	operator	string	The operator or function to apply.
; 	class		int	The class of operator (function or op

; 				be determined from the rest of the
; 				elements.
; 	arg_count	int	How many arguments.
; 	arglist		pointer	A pointer to a list of arguments for
; 				the operator
; 	extras		ptr	A pointer to any keywords (function
; 				ops only).
;	array_count	int	The number of elements returned by
;				any array returning arguments.
;	sequence	objref	The generated sequence.		
; 	is_cumulative	byte	A flag to indicate if the operator
; 				returns a sequence or an image.
