1.  setup_genomicscore.sh : This scripts downloads sources for samtools, bcftools, bedtools, bwa, and vcftools compiles them using `make'.  Additionally, it downloads binaries for bowtie1, bowtie2 (2.1.0), tophat2, and cufflinks.  Finally, it downloads python libraries used by HTSeq, matpotlib and numpy; and HTseq. It also creates a $HOME/bin and $HOME/scripts, and a $HOME/programs where everything is build.
