 The `popup` call `popup_no_wait` or `popup_non_blocking` will create a popup window and then immediately return control back to you.  You can turn other popup calls into non-blocking popups if they have a `non_blocking` parameter.  Setting `non_blocking` to True will cause the function to return immediately rather than waiting for the window to be closed.
 
 This function is very handy for when you're **debugging** and want to display something as output but don't want to change the programs's overall timing by blocking.  Think of it like a `print` statement. There are no return values on one of these Popups.
