get_submissions() error

[dhicks]

It looks like the URLs are constructed inconsistently across different functions. In get_submission() the URL is constructed as

url <- sprintf("%scourses/%s/%s/%s/submissions", canvas_url(), 
        course_id, type, type_id)

which leaves out a / between the result of canvas_url() and the course/:course_id/... part.

It looks like the helper function make_canvas_url() is intended to be used to construct URLs more simply and consistently, eg, in get_assignment_list():

url <- make_canvas_url("courses", course_id, "assignments")
