The following are a list of scoreboards, and how they are used.  Many are not listed, since tampering with them will is usually not a good idea.

ep.uid - an entities ep.uid score is an entities identification number assigned to keep track of it.
This is the value markets/uis look at to link to the actual player who owns the shop.
Changing this score should only be done to re-link a player to an older id, if their id score is reset for some reason.

ep.owner - an markets owner value determines the ep.uid of the owner of the shop.

ep.money - the actual stored money of a player. (should always be a positive integer)

ep.debt - the amount of debt a player has accumulated (should always be a negative integer)
