// ========================== CStream ===========================
// Each streamable class should be derived from CStream
// and have constructor CClass(PCStream & Object), which should
// initialize all memory of the class, and virtual functions
// read(..) and write(..) (see below). Constructor CClass(PCStream&)
// must not touch the Object variable. This constructor is used
// only once just before the read(..) function. It is assumed that
// read(..)/write(..) functions of the CClass provide storage/reading
// of all vital data. Function read(..) must read data in exactly
// the same way as function write(..) stores it.
// For using CClass in streams, three following functions should
// be supplied:
//
// 1.
// void StreamWrite ( CFile & f, PCClass & Object ) {
// StreamWrite ( f,(PCStream)Object );
// }
//
// 2.
// PCStream CClassInit ( PCStream & Object ) {
// return (PCStream)(new CClass(Object));
// }
//
// 3.
// void StreamRead ( CFile & f, PCClass & Object ) {
// StreamRead_ ( f,(PCStream)Object,CClassInit );
// }
//
// All these functions are automatically generated by macros
// DefineStreamFunctions(CClass) -- in the header -- and
// MakeStreamFunctions(CClass) -- in the implementation body. Note
// that macro DefineClass(CClass) should always be issued for
// streamable classes prior to the stream-making macros. Then
// CClass may be streamed using functions #1 and #3.
// StreamRead will return NULL for Object if it was not in
// the stream. If Object existed before calling StreamRead(..)
// but was not found in the stream, it will be disposed (NULL
// assigned).
