code for lesson 24 remote method invocation

Hi Yakov, 
My name is Maxim Markin, i read your recent article in your blog that you started working on second edition of "Java Programming 24-Hour Trainer” book. I read it in 2012 and learn from it a lot. Now i am working as a java developer in Moscow and decided maybe my code will be helpful for the second edition.
I prepared very simple example of RMI call for lesson 24.

You can contact me directly by email maxormo@outlook.com.
Thank you in advance, Maxim Markin.
