SimpleDraw is a new 2D graphics drawing product.  We are asked to write the core engine of the graphics system.
 
You must create software that implements the abstraction of a drawing.  A drawing is defined as a 2D space that contains an unlimited number of drawing primitives.  There are 2 drawing primitives defined:
 
1. An ellipse
2. A rectangle
 
Your software must represent a drawing containing an unlimited number of drawing primitives.  Each primitive has a location (x, y coordinate) and a size (width, height).  The drawing should be able to determine the size of the total drawing and should be able to display the drawing in the following format:
 
Drawing Name: Drawing 1
Total number of primitives: 59
Total size: 1020, 2780
 
Primitive 1: Ellipse
Location: 0, 10
Size: 100, 400
 
Primitive 2: Rectangle
Location: 30, 78
Size: 500, 800
 
.....
 
Primitive 59: Ellipse
Location 100, 600
Size: 300, 333
