In particular how it's done in this code, where it's outside the definition of the plugin and binding events.
Plugins should be built in a way where it is explicitly invoked by the programmers using them, and the 'proper' way is to invoke them from within a $(document).ready() function that is specified by the user in the order that the user wants.
Lets pretend, for example, that this plugin is invoked from within another $(document).ready(), in which case the document.ready call from within the plugin is completely redundant and useless.
