This PR is an attempt to address issues such as #185. I did two separate things:
SphericalCirclepatch class that can be used to plot true cicles in spherical coordinates - where by true I mean that they are the collection of points within a certain angle of a fixed point. Note that these can still look distorted in images due to the spherical projection, or distortion terms in the headers.SphericalCircle@hamogu - since you are familiar with this issue, having reported #185, could you review this? A build of the new docs is available here: http://wcsaxes.readthedocs.io/en/spherical-patches/overlays.html - please let me know if I can make this clearer anywhere!
