	Plug-in name: block_course_daterollover
	
	Plug-in description:
	
	The plug-in adjust assignment dates according to the course start date, 
	it will set forward assignment items by x number of days, which includes allowsubmissionfrom,
	due-date, cutoffdate, upcoming events, in a course through one centralized screen  
	rather than having to go into each individual assignment activity. 
	This started as a fork from TsedeyT's original work.
