Install script makes hg19 and iobio dirs in root directory rather than $DNASCAN_DIR

Hi I just tried to install ALSgeneScanner using the install script and found that it tried to make the hg19 and iobio dirs in my root directory rather than $DNASCAN_DIR. Maybe changing the line from 'mkdir iobio' to 'mkdir $DNASCAN_DIR/iobio' would fix it?
