Unknown units in return value for get_alt_az

[gerritholl]

Code Sample, a minimal, complete, and verifiable piece of code

pyorbital.astronomy.get_alt_az(datetime.datetime.now(), atleast_1d(10), atleast_1d(0))

Problem description

It is unclear how to interpret the values -0.17 and -1.26. It's either a correct value of unknown unit, or it's simply wrong. Maybe it's both in radians?

Expected Output

I expect the documentation to describe the units of the angles.

Actual Result, Traceback if applicable

(array([-0.17020899]), array([-1.25844873]))

Versions of Python, package at hand and relevant dependencies

pyorbital v1.3.1.

@gerritholl thanks for reporting this, you are absolutely right, this should be documented.
