This serves as a bridge between the new and old joblist code.

ColumnResults are column data created from the TableBands
|
|
returned by the NJL. In getSysData, we convert TableBands
|
|
to NJLCR's to avoid having to rewrite all of the systemcatalog
|
|
code that used the old ColumnResult class. It only implements
|
|
the part of the ColumnResult API used by the system catalog.
|
|
Hack as necessary.
