Add Metabox to plugin template

I would like someone to create a custom post type, add a metabox and a custom field in the metabox using the classes and functions in this plugin. [login to view URL] The readme explains how to create a custom post type, and its pretty easy,. The class in /WordPress-Plugin-Template/includes/lib|[login to view URL] has an add_meta_box function but I haven't been able to figure out how to use it. The completed project will be a plugin with a custom post type, which has a metabox in the edit area for that post type, and a custom field in that metabox which will be saved when the post type item is saved. You must must the functions in the plugin as much as possible, or add some functions to the existing classes if something is missing.
