Data::ICal::Entry::Todo - Represents a to-do entry in an iCalendar file

       Best Practical Solutions, LLC <modules@bestpractical.com>

       A Data::ICal::Entry::Todo object represents a single to-do entry in an iCalendar file.  (Note that the
       iCalendar RFC refers to entries as "components".)  It is a subclass of Data::ICal::Entry and accepts all
       of its methods.

       In addition, "due" and "duration" may be specified at most once each, but not both in the same entry
       (though this restriction is not enforced).

       Or if "vcal10 => 1":
