This function takes in the subcomplexity graph from the transfer excess courses function, then finds the transfer delay factor. The output is the sum of the longest paths of prerequisites through courses related to those beyond the expected time to degree.
transfer_delay_factor(plan_of_study, expected_time_to_degree)Numeric - the transfer delay factor
igraph object - An igraph object created using the create_plan_of_study function
Numeric - The term where students are expected to finish (often 8)
