; NAME: PROJECT_SUBTITLE
; PURPOSE: Examine the structure given by the input parameter, and return
;          a string to be used as a subtitle giving project information,
;          and write this string onto current plot.
; CALLING SEQUENCE:
;       project_subtitle,a,title
; INPUTS:
;       a = structure containing a variable from the type of structure
;           returned by the read_mycdf procedure.
; OUTPUTS:
;       title = the string written to the plot or gif.
; KEYWORD PARAMETERS:
;       IMAGE    = special processing for image-type displays
;       TIMETAG  = epoch value associated with a single image

; MODIFICATION HISTORY:
;       8/7/96  R.Burley    ; Add TIMETAG keyword
;     10/21/97  R.Baldwin   ; Add SSCWEB keyword
