# Post1 --- author --> Author1

# So if we did an add Author2 and connect the author to Post1, that changes the 
# author of Post1 to Author2, we need to
#  * add edge Post1 --- author --> Author2 (done by asIDReference/asXIDReference)
#  * add edge Author2 --- posts --> Post1 (done by addInverseLink)
#  * delete edge Author1 --- posts --> Post1 (done by addAdditionalDeletes)
#
# This delete only needs to be done when there is a singular edge in the mutation:
# i.e. if both directions of the edge are [], then it's just an add.
#
# There's three cases to consider: add by ID, add by XID, deep add
