	Determines all the sections for a course including
	sections with students and sections containing other roles.
	Incoming parameters: domain, course number, reference to
	section hash (keys to be section/group IDs), reference to
	array containing roles for which sections should be gathered
	(optional). If the fourth argument is undefined, sections
	are gathered for any role.

	Returns number of sections.
