/*

1.) Modify code to support a Console Logger class that prints to console output window

2.) Inverse the control on logging class dependancies

3.) Correct any other minor problems you see with the implementation (e.g. naming convention, access modifiers, etc)

​

Remember, ask questions if you are don't understand the problem.  This is intended to be collaborative and fun!
