+Declares the cPrefab class, representing a cPiece descendant for the cPieceGenerator that
+uses a prefabricate in a cBlockArea for drawing itself.
+The class can be constructed from data that is stored directly in the executable, in a sPrefabDef structure
+declared in this file as well; the Gallery server exports areas in this format.
