;NAME:
; thm_ui_dproc
;PURPOSE:
; A widget interface for calling tplot from the themis_w widget,
; currently of limited usefulness, but expandable
;CALLING SEQUENCE:
; thm_ui_dproc, master_widget_id
;INPUT:
; master_widget_id = the id number of the widget that calls this
;OUTPUT:
; none, there are buttons to push for plotting, setting limits, not
; sure what else yet...
;HISTORY:
; 06-may-2008, cg, added check to validate data, any active data that
;                  has dimensions ge 3 cannot be processed
;                  added data check for despike, time deriv, wavelet, 
;                  powerspec, active data that has a y component > 6 
;                  cannot be processed
;                  and finally, rearranged widgets to allow for a long
;                  narrow message window
; 28-mar-2008, cg, added filename dialog box to ascii save option,
;                  and passed file name to tplot_ascii
; 14-dec-2006, jmm, jimm@ssl.berkeley.edu
; 13-feb-2007, jmm, fixed problem with !p.background resetting in
; set_plot commands
; 12-mar-2007, jmm, Added wavelet button
; 2-apr-2007, jmm, Added pwrspc options
; 5-jun-2007, jmm, rewritten
; 12-jul-2007, jmm, added a message widget, for invalid user input
;                   errors, grays out all buttons while processing
; 31-jul-2007, jmm, changed time limits to 'set time limits'
; 17-mar-2008, jmm, changed smooth option to input seconds, not npts
