 your task is 
1. Acquire complete versions of Cylinder.h and Cylinder.cpp from Part 1. You may use my Part 1 solution, or your own solution.

Complete add, display, and scale functions for Composite.
Complete the Big-3 for Composite

Note that the Composite::allPolyhedra attribute, is a vector of pointers (std::vector).
I was feeling generous and provided you the Composite::operator= method (I used the copy-and-swap idiom). This leaves you with the Copy Constructor and Destructor (2 of the Big-3).

 
If you implemented everything in Composite correctly you will see:
PASSED->testDefaultConstructor
PASSED->testAdd
PASSED->testClone
PASSED->testRead
PASSED->testScale
PASSED->testDisplay

 If you see FAILED you must revisit revisit the corresponding function(s).  

Many students forget to scale the bounding boxes. This can be done using the BoundingBox::scale or Polyhedron::scale functions.
