## job.queue_task() -- submit a task to run within the job

`queue_task(taskobj)`

> This adds the given `task` object to the job's queue. All tasks in the queue can later be run with job.run_all_tasks().

> The task should be a instance of a class derived from `task`, which provides a `'run'` method. This method will be run on the slave node; any arguments to this method are given on the master when the object is created, and are automatically passed for you to the slave. Anything you return from this method is automatically passed back to the master. (Note that communicator.send_data() is used to send this data, which cannot send all internal MODELLER types.)

> Note that generally you need to declare tasks in a separate Python module, and load them in with the `import` statement, as the tasks are passed using Python's `pickle` module, which will otherwise give an error such as `'AttributeError: 'module' object has no attribute 'mytask''`.

Example: See job.run_all_tasks() command.
