Fixed dependency installation bug

Dependencies should actually install properly now when aionasa is installed from PyPI.

Introduction of EPIC and Exoplanet

I'm happy to announce aionasa's next major development release, version 0.2.0!

The module now covers 5 NASA APIs:

• Astronomy Picture of the Day (APOD)
• InSight Mars deather data
• Earth Polychromatic Imaging Camera (EPIC)
• Near Earth Object Web Service (NeoWs)
• Exoplanet, NASA's exoplanet archive database

Updates to docs, setuptools, etc

Not much changed since 0.1.1, but I'm bumping to push updates setup.py and conf.py so github, pypi and readthedocs are all synced with respect to version.

First PyPI release - APOD and InSight

APOD and InSight are working and documented. Releasing to PyPI as a development version.

First pre-release [APOD]

Currently only the APOD API is complete and documented. This release was created more as a marker for versioning than with the intention of people actually using this library yet.

Of course, anyone is welcome to contribute or help test if interested. APOD is ready to be tested and, while this is the first "real" release, will probably be significantly modified in the near future based on feedback.
