%???in?=?inpoly（pnode）;
%
%???p???:?The?points?to?be?tested?as?an?Nx2?array?[x1?y1;?x2?y2;?etc].
%???node:?The?vertices?of?the?polygon?as?an?Mx2?array?[X1?Y1;?X2?Y2;?etc].

%?EXAMPLE:

%???polydemo;???????%?Will?run?a?few?examples
%
%?See?also?INPOLYGON

%?The?algorithm?is?based?on?the?crossing?number?test?which?counts?the
%?number?of?times?a?line?that?extends?from?each?point?past?the?right-most
%?region?of?the?polygon?intersects?with?a?polygon?edge.?Points?with?odd
%?counts?are?inside.?A?simple?implementation?of?this?method?requires?each
%?wall?intersection?be?checked?for?each?point?resulting?in?an?O（N*M）
%?operation?count.
%
%?This?implementation?does?better?in?2?ways:
%
%???1.?The?test?points?are?sorted?by?y-value?and?a?binary?search?is?used?to
%??????find?the?first?point?in?the?list?that?has?a?chance?of?intersecting
%??????with?a?given?wall.?The?sorted?list?is?also?used?to?determine?when?we
%??????have?reached?the?last?point?in?the?list?that?has?a?chance?of
%??????intersection.?This?means?that?in?general?only?a?small?portion?of
%??????points?are?checked?for?each?wall?rather?than?the?whole?set.
%
%???2.?The?intersection?test?is?simplified?by?first?checking?against?the
%??????bounding?box?for?a?given?wall?segment.?Checking?against?the?bbox?is
%??????an?inexpensive?alternative?to?the?full?intersection?test?and?allows
