Moving functions from octave to octave-forge?

[Søren Hauberg]

Hi,
  When I look at the Table of Contents of the manual, I see some 
chapters that seem very specialized to me. This makes me wonder if some 
parts of Octave should be moved to packages at octave-forge? To be more 
specific I'm thinking about:

* Financial Functions
* Control Theory
* The colour conversion function in Image Processing
* Quaternions

Of course I'm biased by my own usage of Octave, and I realize that it's 
hard to determine what should be in Octave.
