Update utt4gic.pl

THIS SCRIPT TAKES AS INPUT A 4-BYTE BINARY CHROMOSOME FIlE (chrN.znt4) THAT HAS BEEN ANNOTATED AND EXPECTS TO FIND IN THE SAME DIRECTORY 2 OTHER BINARY FILES: mark_geneOut.chrN (output from mark_gene.pl) + mark_gene.intCode.chrN (the associated index file). IN ADDITION, IT WILL ALSO LOOK FOR A LIST OF GENES CREATED WITH utt4ic.pl CALLED utt4ic.geneList.chrN.
