I would really like to see an FFT implementation in boost. It should of 
course focus on performance. I also think that interoperability with 
different vector and storage types would be really great. It prevents 
that the user has to convert its data types in different formats (which 
can be really painful if you use different libraries, for example 
odeint, ublas, fftw, ...).
