Feature/packaging

[JeltevanBoheemen]

This PR aims to make a full package out of sastadev.

• Make an installable package of all the sastadev modules, rather than a limited subset.
• Configuration
  • The implementation may seem weird, but I've exhausted options to do it in a different way that ensures both sasta and sastadev run well.
• Proper test architecture
  • Many of the existing 'tests' are skipped because they do not produce a result, the result is dependent on locally available files, or they produce errors. We will aim to fix this at a later date.

For the individual reviewers:

• @JanOdijk

  • This has some implications for how you write and use the code, but I have tried to keep these to a minimum. You will need to install the package locally (see README) to work on it. Also, mind the configuration, both setting and reading it.
  • Please try to follow the installation instructions, and let me know if anything is unclear or does not work. It is probably required that any sastadev references in your PATH are removed, so only the installed package is read.

• @bbonf , @Meesch

  • Can you test this in auchann? Clone, install locally (e.g. `pip install /Users/my_name/projects/sastadev' and run the tests.
  • General code review. Most of the changes are moved files.

This requires minor changes in mwe-query, which should be merged when the PR is done: UUDigitalHumanitieslab/mwe-query#9

[bbonf]

Might be better to use logging.getLogger('sastadev') instead of the root logger, giving more control to downstream users

[JeltevanBoheemen]

Agree. I'll alter the main script a little bit to also work with that configuration.

[bbonf]

I would maybe prefer having no settings by default, and getting an exception that says I have to initialize sastadev before using any of its functionality. (Or at least a warning, in case you don't want to introduce breaking changes)
Otherwise it could be hard to tell whether something was imported before being configured.

[JanOdijk]

Why was this file deleted. The content is needed. Have you moved it elsewhere?

[JeltevanBoheemen]

It is copied to src/sastadev/generatemacros.py. Somehow Git didn't pick register it as move but delete of the old file +create of the new file.
