gattaca classes

[cetienn01]

• updated Gattaca.py script
• updated "gattaca_classes.py" script

[cetienn01]

The initial code in gattaca_classes.py had a flag -t that is not recognized by snpeff and was throwing an error
cmd = ["java","-jar", snpeff['snpeff'], "genes2bed", "-t", Options.genome, ' '.join(genes)]

I removed that flag from the script as it is not needed.
cmd = ["java","-jar", snpeff['snpeff'], "genes2bed", Options.genome, ' '.join(genes)]
