/** \class SchRename

* SchRename is a structure which partially support the concept of USE and RE-

* FERENCE in EXPRESS. Say schema A USEs object X from schema B and renames it

* to Y (i.e., "USE (X as Y);"). SchRename stores the name of the schema (B)

* plus the new object name for that schema (Y). Each TypeDescriptor has a

* SchRename object (actually a linked list of SchRenames) corresponding to all

* the possible different names of itself depending on the current schema (the

* schema which is currently reading or writing this object). (The current

* schema is determined by the file schema section of the header section of a

* part21 file (the _headerInstances of STEPfile).
