# A note on the naming convention used in this module:
#
# As a Dialogue instance can have a number of Dialogues
# the fact that a course can have more than one Dialogue
# instance complicates the nomenclature within the code.
# We want to easily refer to dialogues within dialogues.
#
# For this reason a Dialogue instance is said to have
# a set of Conversations (not dialogues). So the code
# (and the table structure here) uses conversations
# within dialogues. The term "conversation" is just an
# INTERNAL name and it is NOT used in the user
# interface. There is NO need to distinguish between
# dialogue instances and a set of dialogues within one
# dialogue instance from the point of view of teachers
# or students point of view.
