[~pbacsko] Thanks for your reviews.
# Taken care.
# Compare demands ensures entity without resource demand get lower priority than ones who have demands. When both entities has certain demands ( > 0), then there is no actual comparison. Hence the changes are in that way. It has been commented too at class level. Similar to {{FairSharePolicy}} implementation.
# For #3 and #4, yes there are multiple asserts intended to clearly show the expected final ones are passing after asserting all earlier comparison (in the precedence order) has been passed as well. However, I see your point and made the changes by balancing both the views.
