;PROCEDURE:	load_wi_3dp
;PURPOSE:	
;   loads WIND 3D Plasma Experiment key parameter data for "tplot".
;
;INPUTS:
;  none, but will call "timespan" if time_range is not already set.
;KEYWORDS:
;  DATA:        Raw data can be returned through this named variable.
;  NVDATA:	Raw non-varying data can be returned through this variable.
;  POLAR:       Computes polar coordinates if set.
;  TIME_RANGE:  2 element vector specifying the time range.
;  VTHERMAL:	if nonzero, calculates ion thermal velocities.
;  RESOLUTION:	Returns data at a given time resolution.  In seconds.
;  MASTERFILE:	(String) full filename of master file.
;SEE ALSO: 
;  "make_cdf_index","loadcdf","loadcdfstr","loadallcdf"
