Take a table descriptor and apply it / verify it on top of the
table descriptor returned from a database. This is used to ensure
a model's marked up fields are in congruence with the table. Also
checks to ensure the number of columns in the cascaded descriptor
do not outnumber the actual number of columns. Finally with a database
like sqlite which largely ignores column typing it enables the model
to inform the actual Recess type of the column.
