 *
 * @param apiNs name of the namespace the variable remotingApiVar will live in.
 * Defaults to Ext.app
 * @param actionNs name of the namespace the action will live in.
 * @param remotingApiVar name of the remoting api variable. Defaults to REMOTING_API
 * @param pollingUrlsVar name of the polling urls object. Defaults to POLLING_URLS
 * @param group name of the api group. Multiple groups delimited with comma
 * @param fullRouterUrl if true the router property contains the full request URL with
