Epitope prediction : new module added.

-Adds genomic coordinates to predicted epitopes.
-Takes in parsed file generated from  ParseNetmhcOutput.pm and SNVs file as input.
I know @tmooney suggested `status_message` but `status_message` are not shown by default (nor are `debug_message`).  That doesn't mean this is wrong but you may still want to use `warning_message`; you just need to decide how visible you want this to be.  `status_message` are enabled build logs.
