create_probe_or_si_data.py: added comments at beginning. Code now writes
two rows of headers instead of one. Apparently optdis likes this. 

read_write_gene_info.py: added optional argument to read header or not. 

run_optdis.R: init commit.

shellrun_optdis.sh: batch run optdis. 

standardize_gene_expression.py: init commit: to run before optdis.
