Class CDF_Session is removed. Integrated previously but not described: 0029195: OCAF - ensure thread safety for different documents. Static local variables are eliminated in PCDM package. Global documents metadata look-up table and directory of opened documents are removed. Look-up table is maintained now as field in instances of the CDM_Application class. Methods providing iteration by components are removed from class CDF_Store; signature of methods returned Standard_ExtString is changed to return Handle(TCollection_HExtendedString). Support of different "Presentations" of documents is eliminated.
