/** \brief A class representing a task
*
* A "Task" object stores information about a task such as it's name,
* total and session times.
*
* It can log when the task is started, stoped or deleted.
*
* If a task is associated with some desktop's activity it can remember that
* too.
*
* It can also contain subtasks - these are managed using the
* TQListViewItem class.
