;NAME:
; thm_sample_rate_bar
;PURPOSE:
; creates the sample rate bar for overview plots
;CALLING SEQUENCE:
; p = thm_sample_rate_bar(date,duration,probe)
;INPUT:
; date =  the date for the start of the timespan, 
; duration = the duration of your bar in days
; probe = THEMIS probe Id
;
;KEYWORDS:
; outline: set this to 1 to generate a sample rate panel with
;          a black outline rather than no outline
;OUTPUT:
; p = the variable name of the sample_rate_bar, set to '' if not
;     sccessful
