Manuscript revisions

I apologize for being so slow with this.  I made some textual revisions, targeting a Bioinformatics Application Note.  In this case, 2 pages is approximately 1000 plus 1 figure.  With the revisions we're just over 900.

I would recommend including a brief paragraph explaining a bit about the Vireya story, and also a brief concluding paragraph emphasizing the importance of sophisticated high-dimensional visualization techniques to this field.
