Added test case that works in one of two modes: 1) create synthetic document (in old version of OCCT) containing all possible attributes. 2) open the document and compare all attributes with expected values. Fixed reading of TDataStd_NamedData, TDataXtd_PatternStd, and PColStd_HArray2OfReal. Point and curve representations are created even from NULL geometry handles. The code is simplified by abandoning usage of templates from StdObjMgt_ContentTypes class for persistent data elements. Fixed SetAsciiString Draw command failed when the target label contained NamedData attribute.
