    \class QOrganizerTodo
    \brief The QOrganizerTodo class provides a task which should be completed.
    \inmodule QtOrganizer
    \ingroup organizer-items

    A todo is an item which contains information about a task which has to
    be completed.  It might be associated with a particular point in time
    (for example, water the garden tomorrow evening) or it might have no
    specific temporal association (for example, climb Mount Everest someday).

    A todo can reoccur (for example, water the garden every evening) or it
    can occur only once.

    Todos can be used to schedule agenda items or tasks in a meaningful manner.
