Simple debugging

While we're working through practical examples, we'll need a way to print out information and feedback to the console. The term for this is debugging, and C# and Unity provide helper methods to make this process easy. Whenever I ask you to debug or print something out, please use one of the following methods:

• For simple text or individual variables, use a standard Debug.Log(). Text needs to be inside a set of parentheses, and variables can be used directly with no added characters:
