fit_database
************
This is the database for the job that we will be fitting.
All of the dismod_at hold out commands that will be used for the fit
must be executed; i.e., the hold_out column in the data_subset table
is the same as will be used for the fit.

root_database
*************
This is the root node database. It contains the dismod_at tables
that are the same for all the fits in the cascade.

data_include_table
******************
This is the rows of the data table that are included in the fit; i.e.,
the rows that satisfy the following conditions:

#. The node is the node being fit or a descendant of the node being fit.
#. All the covariates are within their maximum difference limits.
#. The hold_out value in the data table is zero
#. The corresponding hold_out value in the data_subset table is zero.
#. The corresponding integrand is not in the option table hold_out list.
