/*
A small hint for ToBeNotify, CommonToBeNotify and ToNotify
Assume that A need notification from B, we can see it as A want buy something from B.
Assume that A need notification from B, we can see it as that A want buy something from B.
This relation is represented in ToBeNotify, a pure relation without any inhertance hierarchy.
Ok, now we assume A have children AA, B also have children BB.
It's okey to order AA to buy something from B, becase AA is the children of A.
This relation is represneted in CommonToBeNotify.
Because B is a businessman, so his children BB also is a bussinessman.
B and BB have the same goods so A can buy his stuff from both of B and BB.
This is the first step executed by ComputeParentsNotifyTable().
In this step, the function expand existing business relations to all possible business relations (expand to businessman's children)
Image there is a candy store, C. Because AA still is a kids.
So AA want to buy something from C. Now C is in his ToBeNotify.
Additionally, A, the parent of AA, force AA to buy something from B, just for A himself.
For AA, he does not need want to buy something from B, but his parent A order he to do.
So AA's ToBeNotify do not have B, but his CommonToBeNotify have B.
This is the second step executed by ComputeParentsNotifyTable().
For AA, his parent's relations also need to be merged after he processed his relations with C like I introduced previously.
Now, AA have a full business list writing all trades he can do.
This is represented as CommonToBeNotify.
In this time, AA's ToBeNotify only have C, but his CommonToBeNotify have B, BB and C.
So now, let we change the view from A to B.
B now can sell something to A or AA. This represent in B's ToNotify.
Because B is a bussiness man, as the children of B, let we assume BB also have capability to sell something.
He initially do not have any bussiness relation, because no one need to buy something from him.
But he is smart, he want to use his parent bussiness relation. He copied his parent relation, B's ToNotify.
Now BB can trade with A and AA, this represent in his ToNotify.
Now A and AA know that BB is children of B and B is their bussiness friend.
So they also can buy something from BB. This result in that BB is added into their CommonToBeNotify.
B want to know whom I can sell something to.
Because a full trades list are created from A side.
The better solution is just ask the guest: do you want to buy something from me?
This operation will fill ToNotify and is implemented at ComputeHierarchyTable().
At the end of this story,
All bussiness man can use ToNofity to see whom they want to sell something to.
ToNofity list have A and all of his children.
And all buyer can use CommonToBeNofity to check who they can buy something from.
CommonToBeNotify have B and all of this children.
ToBeNotify is just a list to indicate the initial bussiness relation and will never used anymore after real relation established.
