What is a Co-Driver Picker? (Short Description)

The Co-Driver picker essentially allows two registrations to be linked together and share an assignment (vehicle,class etc). When using the co-driver picker, the primary driver registers first then the co-driver can come back afterwards and select the co-driver package and use the picker to select which driver they want to share assignments with. I've included additional details about co-drivers  here as well.

Note: The Co-Driver won't appear on the public attendee's list until they have their own assignment / assigner as well.
