addressed]

Comment (by jason):
This is a little puzzling since the code *does* use scipy to do fft. Here
is the relevant call:
{{{
return v._new(scipy.fft(v._vector_numpy))
}}}
The thing that I see is that above this, I do:
{{{
cdef Vector_double_dense v = self.complex_vector()
}}}
I think the wasted time is in one of those two calls. I can look at this
later.
