Configurability of Recurse Levels

My boss gave me a feature request. He doesn't like the menu clutter when the footer is aligned 'center' for a particular client's web site. I should really add in configuration for the module so that the recursive function to grab the menu stops after a certain menu level. This can be set to 0 - only the primary links, 1 - one step down, 2 - two steps down, etc...

This should be a fairly easy feature request once I add a configuration hook.
