Minor Description
PIL is provided on many distributions and there are installers for Windows. Alas, it is not pip installable.
However, a "friendly-fork" of PIL, pillow, is installable via pip. A small change in import is required, `from PIL import Image` instead of `import Image` (likely so they can co-exist).
I've locally added this to tvb/core/services/texture_to_json.py and am currently testing.
Not sure if it would be a good idea to start and extern module which centralizes workarounds for external packages?
