;NAME:
; spd_ui_clip_data_options
;
;PURPOSE:
; Front end interface allowing the user to select options for clipping data.
;
;CALLING SEQUENCE:
; return_values = spd_ui_clip_data_options(gui_id, statusbar, historywindow)
;
;INPUT:
; gui_id: widget id of group leader
; statusbar: status bar object ref.
; historywindow: history window object ref.
;
;OUTPUT:
; return values: anonymous structure containing input parameters for dproc routine
; {
; maxc: maximum value for clipping
; minc: minimum value for clipping
; opts: Array of flags determining extra options
; [clip adjacent points, insert user-specified flag (instead of NaNs)]
; flag: user-specified flag, a double to be insterted where values are clipped
; suffix: Suffix for new variable
; ok: Flag indicating success
; }
