contributing C/Cython code to the scikit

[mael]

Hello everyone,

here is a first code draft, including two basic filters
 http://github.com/maelp/scikits.image

the goal is not to include high-profile algorithms right now, but to
get the base framework correctly (and then we'll have some engineer
translate our codebase to python).
could you tell me if the way I started it seems okay  with
 you? (eg I've been hacking in some files to have everything compile..
am I doing it as it should be done?)

feel free to comment on code and possible  issues , as we're trying to
have some solid base to build upon :)
