corrfactor_continuous(neighbour_list, events, line_list, bws, max_depth)
a list of dataframes, used to calculate the Diggel correction factor
a list of the neighbours of each node
a numeric vector of the node id of each event
a DataFrame representing the lines of the graph
the kernel bandwidth for each event
the maximum recursion depth (after which recursion is stopped)
