[SUGGESTION] Consider making development dependencies optional

[niksirbi]

Some of the dependencies, e.g. pytest and pytest-qt are only required during development, and not needed for users. You could make those dependencies optional under an arbitrary identifier (e.g. dev) in your setup.cfg file.

[options.extras_require]
dev =
    pytest
    pytest-qt

This way pip install systems-neuro-browser will install only the smaller set of "normal" dependencies, whereas pip install systems-neuro-browser[dev] will also include the testing dependencies. In future, if you add linters and or type checking, you could also group those tools under the. dev optional dependencies.

I implemented the dev option exactly as described (https://github.com/calebweinreb/SNUB/commit/7c130749962e90ddbc63207441aaa6dc203d5fa9). Its now available on PyPI for version >= 0.0.14
