Before this patch, executing directly one of these scripts, for example `./plot_hystogram.py` in a unix-like environment meant that the default system-level python would be used, regardless of an eventual activated virtualenv. This was due to the "#!/usr/bin/python" shebang. Changing it to "/usr/bin/env python" is a fairly standard practice, keeps intact the compatiblity with the system level python, and allows a user to run in a virtualenv if he wants.
