Animation

An Animation renders a widget to the screen each time update is called, clearing the render from the previous call.

If you print anything in between calls to update, the rendered widget will be cleared, before the print, then rendered again below it.

Note that Animation doesn't render the widget automatically: you need to call update yourself when your data changes. If your terminal is not interactive, the animation will not render anything.

You can create instances of Animations with animation, textAnimation, animate a progressBarLayout, or by creating a subclass.

Note that although this class's state is thread safe, calling update concurrently will likely cause garbled output, so usage of this class should be serialized.
