The IDLitCommandSet::Init function method initializes the object.
Obj = OBJ_NEW('IDLitCommandSet')
Result = Obj->[IDLitCommandSet::]Init() (In a subclass' Init method only.)
When this method is called indirectly, as part of the call to the OBJ_NEW function, the return value is an object reference to the newly-created object.
When called directly within a subclass Init method, the return value is 1 if initialization was successful, or zero otherwise.
All keywords are passed to the superclass of this object (IDLitCommand).
