+ * Address Controller
+ *
+ * Generally speaking, controllers are the middlemen between the front end of
+ * the CP/website and your plugin’s services. They contain action methods which
+ * handle individual tasks.
+ *
+ * A common pattern used throughout Craft involves a controller action gathering
+ * post data, saving it on a model, passing the model off to a service, and then
+ * responding to the request appropriately depending on the service method’s response.
+ *
+ * Action methods begin with the prefix “action”, followed by a description of what
+ * the method does (for example, actionSaveIngredient()).
