Table Group class is the collection container object used to access and create table groups. Like the table class, table group classes are generated in pairs, a row class, and a collection class.

The naming convention for table group classes is TblGrp<message name><group name> for the collection object, and TblGrp<message name><group name>Row for the row object. i.e. if you had a table group named "Insurance" in a message called "Admit", the classes generated would be TblGrpAdmitInsurance and TblGrpAdmitInsuranceRow.
