function theme_node_recipe in Recipe 5

A custom theme function.

By using this function to format our node-specific information, themes can override this presentation if they wish. We also wrap the default presentation in a CSS class that is prefixed by the module name. This way, style sheets can modify the output without requiring theme code.
