+You can also tweak some of the defaults by creating an initializer
+in <tt>RAILS_ROOT/config/initializers/track_changes_configuration.rb</tt>
+and calling TrackChanges::Initializer.instance which yields a
+TrackChanges::Configuration object:

+  # These are the defaults anyways

+    c.current_user     = :current_user  # Controller is sent this method to obtain current user.
+    c.ignore_nil       = true           # Don't crash if a model is nil.

 if there are any changes, an audit will be created.
