/**
 * This class provides a general interface to sequence related headers.
 * Headers commonly precede sequence data in several file formats.  In
 * FastA files, the header is on the > line before a contig.
 * In GenBank files, each contig has headers describing authors and other
 * information.  In GenBank files, the header name corresponds to the
 * name of the header field.  A few genBank header names are: DEFINITION
 * ACCESSION, VERSION, KEYWORDS, SEGMENT, SOURCE, REFERENCE, and COMMENT.
 * Eventually, individual classes may be implemented for each header type.
