* is executed.
* @param o the context object.
* @param fn {Function|String} the function to execute or the name of
* the method in the 'o' object to execute.
* @param data [Array] data that is provided to the function. This accepts
* either a single item or an array. If an array is provided, the
* function is executed with one parameter for each array item. If
* you need to pass a single array parameter, it needs to be wrapped in
* an array [myarray].
* @param periodic {boolean} if true, executes continuously at supplied
* interval until canceled.
* @return {object} a timer object. Call the cancel() method on this object to
* stop the timer.
