[Bioperl-l] frac_* methods

[Chris Fields]

I think their use is based on what you are trying to accomplish.  For  
instance I am currently running a lot of small BLASTN queries  
(limiting by normalized bit score), so I tend to look at the HSP data  
more.  However, in other circumstances I might want the overall  
frac_identical for all HSPs ($hit->frac_identical).  YMMV.
