;PROCEDURE:	load_po_pwi
;PURPOSE:	
;  Loads Polar Plasma Wave Instrument key parameter data into "tplot" variables.
;
;INPUTS:
;   none, but will call "timespan" if time range is not already set.
;KEYWORDS:
;  DATA:        Raw data can be returned through this named variable.
;  TIME_RANGE:  2 element vector specifying the time range
;
;SEE ALSO: 
;  "make_cdf_index","loadcdf","loadcdfstr","loadallcdf"
