Recurring Assignments

It would be nice to be able to create a recurring assignment that occurs each week or day during a quarter\semester.  During the creation of the assignment, the user has the Assignment type options to select:  One-Time, or Recurring.  If the assignment is recurring, then the user has the recurring type options to select:  Daily or Weekly or Monthly.  If the user selects weekly, they have the options to specify which day of the week the assignment occurs on for each week.  If the user selects Monthly, they have the option to select the date within a month that the assignment will recur on.  The user should also have the option to provide a date for any recurring assignment to stop. This date should be the last day that the recurring assignment is available.  Also, for all recurring assignments, the grade book should have a column for each recurring assignment so grades can be recorded for them.
