def get_next_recommendations(user, request):

    ''''Get the recommendations for the Next section, and return them as a list.
    Logic:
    Next recommendations are currently comprised of 3 main subgroups: group recommendations,
    struggling exercises, and topic tree based data. Group recommendations consist of
    finding the most common item tackled immediately after the most recent item, struggling
    is determined by the "struggling" model attribute, and topic tree data is based off
    the graphical distance between neighboring exercise/topic nodes.
    Args:
    user -- The current user as a facility user model object.'
