Comment:
Doctests pass and documentation builds. Numerics look good. A few problems
resulting from the merge conflict resolution:
1) A line has been modified in `hypergeometric.py`. This modification
appears to be inaccurate and has the wrong variable anyway. Please remove
the condition `x>0` on `hypergeometric_U`.
2) The definition of the spherical Bessel function of the second kind has
been left behind in `special.py` after the definition of spherical
harmonics. This one needs to be deleted since it's already in `bessel.py`.
3) The evaluation of spherical harmonics has changed. I'm assuming this is
because `meval` is gone, but please confirm. This change has no apparent
problems.
4) There are doctests added to the complete elliptic integral which are
outside this ticket. Since they pass I'm fine leaving them here, but let
me know that they are included just to avoid an extra ticket.
