- Provide DumpJson for geometrical, ocaf and visualization classes; - Change depth parameter of DumpJson (constant is not obligate here) - Introduce a new macro for transient objects to be called as the first row in DumpJson: OCCT_DUMP_TRANSIENT_CLASS_BEGIN. We need not put the class name in the macro, using get_type_name of Standard_Transient for it. - change implementation of OCCT_DUMP_CLASS_BEGIN and OCCT_DUMP_TRANSIENT_CLASS_BEGIN. It is not an sentry more and it does not create a new hierarchy level. It appends a new row into the output stream: "className": <className> - OCCT_DUMP_* does not require semicolon - class header is included first in source files of TDataStd, TDocStd, TCAFDoc
