Ruby Concepts - Singleton Classes

Have you ever wondered what a "singleton class" is? Have you ever been talking to someone or reading a blog post and "singleton class" or "singleton method" got used, and you just smile and nod, making a mental note to look it up later? Now is your time. Now is your moment. I'm hoping to explain this concept in more intuitive language and show you how handy it can be.Side note: a lot of this information came from reading The Well-Grounded Rubyist by David A. Black. This book has a ton of great information and is currently one of my favorite books on Ruby.Side note .
