Re: knngist plans

Marios,

you're right. There are several reasons for poor documentation, but of course,
no excuse, we do need good docs any way ! It's very nice you're willing to
write one, since it's always better seen from outside of development.
I think it'd be better to use wiki, so other people can join.
Pictures would be nice, but I don't know if there is consensus about using
pictures in documentation.

Oleg

btw, we're thinking in the background about new indexing infrastructure -
Spatial GiST, but it's rather big project, so we need sponsors.
