% function [CornersFound] = FindCorners(x,y,threshhold,closed)
%
% inputs: x(1:n),y(1:n) are the coordinates of n points on a
%         curve,
%         0 < threshold < pi is the angle defining a corner: if
%         the interior angle theta between succesive segments in
%         the polygon satisfies theta<=pi-threshhold then
%         the point is declared a corner,
%         closed = 1 if the curve is to be considered a closed curve,
%                  0 if not.
% Note: at this point we do not assume x(n)==x(1) or y(n)==y(1) for
% closed curves.
%
% outputs: CornersFound: a list, in order, of indices into x,y indicating
%          points identified as corners.
%
% This function depends on the function "IntAngle"
