Feedinlib

This release fixes the issue that version 0.0.11 has been dysfunctional when installed as a package because of API breaks in the windpowerlib. It will also be the last release of the feedinlib as it is. We will start working on a new feedinlib that will essentially be an interface to weather data sets and perspectively libraries like the pvlib and windpowerlib. See 29 to get some more information.

Wind power calculations have been outsourced to the wind-python/windpowerlib. Also, due to some technical problems of an external server, the external data has been moved to the feedinlib in order to be independent of external sources.

So far the feedinlib could only be installed under python 2.7, 3.3 and 3.4. This restriction has been removed since it also works with newer python versions and might work with python versions <2.7. We will always specify with which python versions it was tested and will therefore definitely work, but feel free to use/test it with your installed version.

Due to some changes in the pvlib API we had to adept the feedinlib, too. So use `pip3 install feedinlib --upgrade` to update the feedinlib and the pvlib.

When we started the feedinlib, the pvlib was a only a toolbox. But things change and now a ModelChain class exist that allows us to shorten the feedinlib code. In cooperation with the pvlib it is planned to move most of feedinlib's extra code directly to the pvlib. This could avoid incompatibility problems in the future.

This release was necessary because the URL of the sandia module library changed and the feedinlib depends on the library. You can also enjoy same small features and some documentation updates.

Some inconveniences are fixed and the documentation is cleared up a bit. We hope that it is now easier to use the feedinlib. We still working on the models. The results at some places still differ a lot from reference calculations.
