__pycache__ in caiman_data?

[pgunn]

This is to track a concern I've seen with build-it-yourself caiman installs that these directories all get a pycache subdirectory:

• bin/
• demos/notebooks/
• demos/general/
• docs/source/

It's probably harmless, and I'm not sure if we need to care, although I'd like to have it not there for conda builds at least.

If we wanted to change it, we're looking at changing caimanmanager.do_install_to() we could probably modify shutil.copytree to use the ignore=ignore_patterns(...) argument, and replace the distutils call with intelligent use of dirs_exist_ok in copytree (which maybe we should do anyhow).

I think this must be something with newer versions of the package build libraries (pip? distutils? setuputils?); I know it didn't happen before with compiled versions of caiman.

I wonder if having setup.py do an

os.environ['PYTHONDONTWRITEBYTECODE'] = 1

early on would prevent this.

pip explicitly builds those, so the env var route is no good. Going the caimanmanager route described above
