Subject: create new Genome directory and add files
X-Git-Url: http://demsky.eecs.uci.edu/git/?a=commitdiff_plain;h=200429af1ad2fe06490d7f5730ad4f7f8c9962fc;p=IRC.git
create new Genome directory and add files
clean up the comments
change C longs -> ints
works fine for singleTM version with all compiler optimizations
