defines Group, Type <402> Form <1>
in package IGESBasic
The Group Associativity allows a collection of a set
of entities to be maintained as a single, logical
entity
Group, OrderedGroup, GroupWithoutBackP, OrderedGroupWithoutBackP
share the same definition (class Group), form number changes
non Ordered, non WithoutBackP : form 1
non Ordered, WithoutBackP : form 7
Ordered, non WithoutBackP : form 14
Ordered, WithoutBackP : form 15
