An auxiliary table contains statistical information on the
relative frequency of different quasi-identifiers values. It has one or
several quasi-identifiers columns, and one column that indicates the
relative frequency of each quasi-identifier tuple. If a tuple is present
in the data but not in the auxiliary table, the corresponding relative
frequency is assumed to be zero (and thus, the tuple is highly
reidentifiable).
Required. Quasi-identifier columns.

QuasiIdField
A quasi-identifier column has a custom_tag, used to know
which column in the data corresponds to which column in the statistical
model.
