    Define GlRowEntry object and it's API
    
    The GlRowEntry object includes flags/variables to store information
    about the compression of journal entries and pass it on from the
    model to view.
    
    There are three types of row entries: uncompressed, compressed, header.
    
    If a row entry is a header, then it also stores the compressed
    journal entries which are represented by the header.
