CORBA35 — add some feature to let an assembly look like a monolithic compoment

It is better to add some feature to let an assembly look like a monolithic compoment. For example, add some discriptions in CAD(compoment assembly discription) file to identify the external interface of an assembly. There exists an delegate compoment behaving like the assembly. It can navigate one external interface of an assembly to another. This delegate compoment can be created by main component server automatically according to the CAD file.
