Some suggestions for the docs

1. As Ipython is not a requisite for healpy, I would suggest to change the small example/test in the installation instructions to pure python.

2. In the spherical harmonics functions docuentation, "synfast" appears under "From map to spherical harmonics" and "anafast" does under "From spherical harmonics to map". They should exchange positions.
