How to use the astroplan.target.FixedTarget.from_name function in astroplan

The way this setup works is that for functionality that usually requires
    internet access, but has mocks in place, it is possible to write the test
    without adding a `@remote_data` decorator, and `py.test` will do the right
    thing when running the tests:

    1. Access the internet and use the normal code if `--remote-data` is used
    2. Not access the internet and use the mock code if `--remote-data` is not used

    Both of these cases are tested on travis-ci.
