SunPy : Re-implementation of sunpy.wcs as sunpy.coordinates using astropy

by Asish Panda for Python Software Foundation

The current sunpy.wcs has methods defined for transformation of different solar coordinate frames. But they do not support transformation between different coordinate representations. This project aim to re-implement the sunpy.wcs as sunpy.coordinates, basing the implementation on the idea described in APE5. Doing so, it hopes to achieve a much more user-friendly interface with the coordinate systems, as well as adding more functionality to the existing SunPy.
