// .OBJ Loader
// by SAITO <http://users.design.ucla.edu/~tatsuyas> 
// Placing a virtual structure represented as mathematically 
// three-dimensional object.
// OBJModel.load() reads structure data of the object stored 
// as numerical data.
// OBJModel.draw() gives a visual form to the structure data.
// processing standard drawing functions can be used to manipulate
// the visual form to create deep visual experiences.
