[Genome] CpG islands feature is exon

[Ann Zweig]

Hello Robert,

	It does seem a little surprising that the third column of the GTF file 
is "exon".  However, the data in the file is correct.  You can think of 
that field as filler (it had to place some feature name in there, so it 
chose exon).  Read more about the GTF (and GFF) file formats here:
