00114     Created:    9/4/97
00115     Purpose:    The HTML export filter base class.
00116 
00117                 This filter itself will not be added into the filter system - 
00118                 derived classes of this will be added. At the moment, the
00119                 only derived class is ImagemapFilter.
00120 
00121                 This class contains the functionality for writing out
00122                 HTML tags.
