Published 1.0.67
Added AdditionalIds field on selectcolumn.
Added optional controls to display number of selected rows

Currently there is a "Select None" link that is functional, but there is
not a "Select All" as that feature requires more discussion about
implementation.

grid's secondaryDataFields.

Also added ID's to each row of sample data.
