//  Release 3.02.06
// Here is the format of a class object in DATA that uses the default streamer.
// Objects of many classes with custom streamers can have very similar formats.
//----------------
//  0->3  ByteCount = Number of remaining bytes in object (uncompressed)
//        | OR'd with kByteCountMask (0x40000000)
//  4->.. ClassInfo = Information about class of object
//        | If this is the first occurrence of an object of this class in the record
//                       |  4->7  -1        = New class tag (constant kNewClassTag = 0xffffffff)
//                       |  8->.. Classname = Object Class Name (null terminated string)
//        | Otherwise
//        |  4->7 clIdx      = Byte offset of new class tag in record, plus 2.
//        | OR'd with kClassMask (0x80000000)
//  0->3  ByteCount = Number of remaining bytes in object (uncompressed)
//        | OR'd with kByteCountMask (0x40000000)
//  4->5  Version   = Version of Class
//
// The rest consists of objects of base classes and persistent non-static data members.
// Data members marked as transient are not stored.
//
//  6->.. Sequentially, Objects of each base class from which this class is derived
//    (rarely more than one)
//  0->.. Sequentially, Objects of all non-static persistent data members.
//
// Class objects are broken down recursively as above.
//
//      Built in types are stored as follows:
// 1 Byte: char, unsigned char
//      2 Bytes: short, unsigned short
//      4 Bytes: int, unsigned int, float
//      8 Bytes: long, unsigned long, double
// Note that a long (signed or unsigned) is stored as 8 bytes even if it is only four bytes
//  in memory.  In that case, it is filled with leading zeros (or ones, for a negative value).
//
