Noop Task

The <noop> task says that nothing should be done (noop stands for “no operation”). This tag is
used to override deck-level elements.
The <do> tag can be used to activate a task when the user clicks on a word/phrase on the screen.

Example: The example below uses a <do> tag to add a "Back" link to the card. When the
user clicks on the "Back" link, he or she should be taken back to the previous card. But the <noop>
tag prevents this operation; when the user clicks on the "Back" link nothing will happen:
<?xml version="1.0"?>
