title: Is there a way to have the PowerShell screen clear itself before each command?
body: <p>I'm playing around with <em>PowerShell</em> and I find myself constantly typing <code>cls</code> before I run commands. Or worse, I run a command, realize that the output from other stuff is making it a pain to navigate, run <code>cls</code>, and rerun my darn command.
  Is there a way to have the previous command's output cleared before running each command? Obviously it would be ideal if this could be toggled with a command or something simple, but whatever would work. :)
  Also, I'm playing with <em>PS 3</em>, <em>ISE</em>, and <em>PowerGUI</em>.</p>
