module base.managers {

    export class EventManager{

        //CUSTOM EVENT CONSTANTS

        ERROR_CATALOG_LOADED:string =   "APP_ERROR_CATALOG_LOADED";
        ERROR_LOGGED:string =           "APP_ERROR_LOGGED";

        USER_REGISTER:string =          "APP_USER_REGISTER";
        USER_LOGIN:string =             "APP_USER_LOGIN";
        USER_SAVE_ITEM:string =         "APP_USER_SAVE_ITEM";
    }

}

Notes:
We keep an instance of underscore at base._

Use:
base.events = new base.managers.EventManager();
base.events.on( base.events.APP_INIT , baseAppInit );
base.events.trigger( base.events.APP_INIT );
