%% Specifying Faces and Vertices
% Create a single polygon by specifying the coordinates of each unique
% vertex and a matrix that defines how to connect them. Then, add two more
% polygons to the figure. 
%
% Create a red square with corners at |(0,0)|, |(1,0)|, |(1,1)|, and
% |(0,1)|. Specify |v| so that each row defines the (_x,y_) coordinates for
% one vertex. Then, specify |f| as the vertices to connect. Set the color
% by specifying the |FaceColor| property.
