function [Winfo,spec2d,fd,thetad,td]=specmultiplot(dateinfo1,dateinfo2,timestep)
%where dateinfo1 and 2 are the strings of the first and last date extension
%of the pressure,range,etc files and timestep is the time in hours between
%each burst

%This function takes the pressure, range, orbit and sysinfo files created
%in python and outputs a Winfo data structure with the sig wave height,
%peak period, direction of peak period and dominant dir.  It also generates
%polar plots and 2d freq and directional plots of a variety of different
%estimation methods. 

%%% IMPT NOTE!!! The ADCP height above bottom is manually set in the
%%% radialtouvw.m and the radial.m code.  In this case the default is set
%%% at .4m  This will be changed in a future release!!
