/**
 * This class allows you to estimate the score for your solution before handing it in.
 * 
 * This class also generates the required submission package to hand your solution in.
 * 
 * In order to run this AutoGrading application, in Eclipse, Right-click on it->Run As->Java Application
 * 
 * 
 * Please read the instructions that the application prints very carefully. It will store the generated
 * solution submission packages in the coursera-submission folder within the project directory. After running
 * this application, you will need to right-click on the root of the project in Eclipse->Refresh to see this 
 * folder inside of Eclipse. Each time that you run this application, it generates a new unique submission
 * package. Make sure that you submit the correct (e.g., most up to date) package when you turn your assignment
 * in.
