function?[thetaphi]?=?angulargrid（nthetanphibehaviour）
%?angulargrid.m?-?makes?a?grid?of?point?in?theta?and?phi
%
%?Usage:
%?[thetaphi]?=?angulargrid（n）;?[n?=?ntheta?=?nphi]
%?[thetaphi]?=?angulargrid（nthetanphi）;
%?[thetaphi]?=?angulargrid（nthetanphibehaviour）;
%
%?The?default?behaviour?is?that?theta?and?phi?are?returned?as
%?column?vectors?of?the?points.
%
%?Use?behaviour?to?control?the?output?type:
