# TODO
# If an activity has splits defined at the activity,
# * And then some transactions with no values set
# * But some transactions with values set
# The results should be:
# * The transactions with no values set should be split
# * The transactions with values set should NOT be split
# We should test this
#
# Also what happens if a transaction has some values set but not all of them?
# eg. An activity has sector and country splits set, but then a transaction only has country set.
# Should that transaction be split by sector but not country? Test.

(Assuming I'm right in my assumptions on how this should work, do check those)
