New description:
This patch add's Riemann mapping functionality to sage:
http://en.wikipedia.org/wiki/Riemann_mapping_theorem
It can compute numerical maps and has multiple utilities for
plotting/visualizing the maps.
It also includes 2 functions to parametrically interpolate lists of
complex points. This makes it far easier for the user to define the
boundary of the figure that they wish to Riemann map.
NOTE: This may require the cython 0.11.2spkg to compile.
EDIT: There was a problem with one of my interpolation equations, fixed it
+ tests. New patch is below first one.

That's a problem with sage's cython version. You need to update to 0.11.2.
According to Mike Hanson:
" There is a ticket to update Cython in Sage at
http://trac.sagemath.org/sage_trac/ticket/6438. If you download
http://sage.math.washington.edu/home/robertwb/cython/cython-0.11.2.spkg
and run "sage -f /path/to/cython-0.11.2.spkg", then Cython 0.11.2 will
be used.
