Is there any chance someone could knock up a quick example of a map with multiple markers in a marker container and a remove button that clears all markers and infobubbles.

I know there's a similar example in the "playground" but it's just too complicated for me to understand because it allows markers to be created on-the-fly. I want to know how to load markers onto the map normally but allow a button to remove all markers and infobubbles from the map.
