OnIdle
======

This is a simple plugin that adds an "on idle" method available to use
in views.  It takes three arguments:

    def on_idle(timeout, options, wakeoptions)

    <%= on_idle(600, {:url => { :action => 'notify_idle' }},
                     {:url => { :action => 'notify_wake' }}) %>


timeout: the number of seconds before the user is considered 'timed
out'.

options: the action to perform when the user goes idle.

wakeoptions: what to do when the user 'wakes up'.
