Learn about PowerShell variables

- As we move from just running commands in PowerShell to writing reusable commands, something that I guess you could call a batch file, or if you want to call it a script, you can, we're going to start using some of the constructs in PowerShell that support this type of behavior. And the first of those is going to be variables. They're a place to store your stuff. And in this module, you'll not only see how PowerShell deals with variables and how you create them and work with them, you'll also see some of the kind of goofy things that people do with variables so that when you're out there looking at other folks' examples on the internet, you'll know what you're looking at.
