Naming of modules and packages

Created by: PRemmen

Following https://www.python.org/dev/peps/pep-0008/#prescriptive-naming-conventions we would need to rename a lot of packages and modules

Modules should have short, all-lowercase names. Underscores can be used in the module name if it improves readability. Python packages should also have short, all-lowercase names, although the use of underscores is discouraged. <

Should we do this? I think it is a huge non backward compatible change in teaser, but thinking of the open-source release it might make sense to think about this now.
