Demonstration of simple and multiple OneLineProgressMeter's
Shows how 2 progress meters can be running at the same time.
Note -- If the user wants to cancel a meter, it's important to use the "Cancel" button, not the X
If the software determined that a meter should be cancelled early,
calling OneLineProgresMeterCancel(key) will cancel the meter with the matching key

The simple case is that you want to add a single meter to your code. The one-line solution
