This function calculates the average sequencing in the program using the delay factors of the courses. The second argument, expected_time_to_degree is optional. If it is not NULL, the average sequencing will be for courses extending the student's time to degree.
average_sequencing(plan_of_study, expected_time_to_degree = NULL)Numeric - the average sequencing in the program
igraph object - An igraph object created using the create_plan_of_study function
Numeric - The term where students are expected to finish (often 8)
