Programmer Evaluation – Step 2 of 3

Given a 2D Entity where each has a Rectangle2D bounding box and optional Components:
• Add a Rectangle2D bounding box member to the Entity.
• Add a collection of Components to the Entity. An Entity may have any number of
Components. Assume there will be more than the three example Components below.
• Write the implementation to make Entity copyable.
• Feel free to modify the existing code as desired.
