duplicated placement data in the attribution table and the ledger scores
table. Means that setting placement in the attribution table is
meaningless. Probably best to remove the placement in the attribution,
or have it reference the placement in the ledger, else return 0. That
would mean that the only way to change the scores is in the ledger,
which is basically what I want, but also if the db dies then there's not
really anything that I can do to recover the scores (same is true for
the attribute table, but I can seed that so it doesn't matter as much).
To get around that, I would need to add seeding the ledger to a seperate
command, which defeats the point of a ledger.
Just add a way to import and export the whole ledger to csv, dumbass.
