Queries for a Single :ref:`idco` Table
This subclass of :class:`core.QuerySet` is used when the data consists exclusively of a single :ref:`idco` format table.
Note
This is similar to the data format required by Biogeme. Unlike Biogeme, the Larch :class:`DB` allows non-numeric values in the source data.
