+Description: Replace tabs in gff files with spaces
+ GFFparsers are supposed to ignore all the text in lines that start with # but 
+ for some reason, gffread doesn't like tabs in comments.
+ The number of tabs after which gffread complains seems to be related to the 
+ following line, but since this is just a comment anyway, replacing tabs with
+ spaces seems like an easier fix.
