"""Checks two courses start & end dates to see whether they can overlap and
hence potentially conflict. If any of the values are passed as None it will
automatically consider that they can potentially conflict. Input type is
string but has to be in a reasonable date format.
Arguments:
course_1_date_start {[string]} -- [course 1 start date in a reasonable date format]
course_1_date_end {[string]} -- [course 1 end date in a reasonable date format]
course_2_date_start {[string]} -- [course 2 start date in a reasonable date format]
course_2_date_end {[string]} -- [course 2 end date in a reasonable date format]
Returns:
[bool] -- [True if if dates ranges of course 1 and 2 overlap, otherwise False]
