/**
 * DrawingStuff
 * The main class for the drawing program
 * 
 * This is an application that allows the user to move objects around the
 * screen to create drawings.  It is a "rough draft", so objects cannot
 * be added via the user interface.  For testing purposes, several objects
 * are added in the addStuff() method.
 * 
 * Right now, it supports 3 object types: Ovals, Rectangles, and Strings.
 * It would be nice if I could add triangles, Polygons, Lines, JPEG images, 
 * etc.
 * 
 * Your job is to get started on this by adding triangles and lines.
 * You may refactor the code and add as many new classes as you need to.
 * Of course, design is of utmost importance, so make wise and informed
 * decisions about your class structure.
 * 
 * You should probably not need to modify this class.
