Main script cannot be executable without a shebang

[ryanrichholt]

The main script here https://github.com/tgen/vcfMerger2/blob/master/bin/vcfMerger2.py will not work unless there is a shebang at the top. It's already executable, but without the right shebang, shells will just try to execute it as a shell script. Add this line to the top of the file:

#!/usr/bin/env python3

• Shebang added to script as first line
