 * @class Ext.Interaction
 * 
 * 
Interactions are very simple objects that represent an action performed by specific {@link Ext.Controller} 
 * action. The must consist of the {@link #controller} and {@link #action} to be called, but can contain any other
 * data too. See {@link Ext.Dispatcher} for more details on how Interactions fit into the application ecosystem.
 * 
 * 
Interactions are an internal representation that most developers will not have much direct use for. They 
 * help provide a normalized API for controller actions - each action should simply be set up to receive an Interaction
 * object. Because Interaction objects are always created when dispatching to a controller action, it is possible to 
 * store the Interaction objects that were created in a session to perform simple analytics on how the application 
 * is used. This is not built into the framework at the moment, but is left open for custom development if needed.
 * 
 * @constructor
 * @param {Object} config Options object containing at least a controller/action pair
