;PROCEDURE:
;  epde_plot_overviews_solo
;
;PURPOSE:
; Loads EPDE, performs pitch angle determination and plotting of energy and pitch angle spectra
; Including precipitating and trapped spectra separately. EPDI can be treated similarly, but not done yet
; Regularize keyword performs rebinning of data on regular sector centers starting at zero (rel.to the time
; of dBzdt 0 crossing which corresponds to Pitch Angle = 90 deg and Spin Phase angle = 0 deg.).
; If the data has already been collected at regular sectors there is no need to perform this.
;
;KEYWORDS:
; trange - time range of interest [starttime, endtime] with the format
;          ['YYYY-MM-DD','YYYY-MM-DD'] or to specify more or less than a day
;          ['YYYY-MM-DD/hh:mm:ss','YYYY-MM-DD/hh:mm:ss']
; probe - 'a' or 'b'
; no_download - set this flag to not download data from the server and use local files only
; sci_zone - if set this flag will plot epd overview plots by science zone (rather than by day)
;            not yet implemented
; quick_run - set this flag to reduce the resolution of t89/ttrace2equator (from 1 sec to 1 min)
; one_zone_only - set this keyword to only plot the first sci zone (this is a kluge for the pink plots)
; regularize - set this keyword to use the regularize keyword when calling elf_getspec
;
;TO DO:
; implement plots by sci zone only
;
