[postgis] 'real' contains, touches, overlaps etc.

[Manuel Weindorf]

Hi,

Fist I have to say that I love PostGIS VERY much, I was working with 
PostgreSQL for a while using it's geometry type but the possibilities 
provided now are much more promising.

One question:
Is somebody actually working on the following operators ???
contain(g1,g2) 
touches(g1,g2)
overlaps(g1,g2)

These functions are important for me (at least concerning the polygon type), 
and so I just started implementing them (based on the postgis-cvs version).
I don't know how far I get but, if there's another one doing the same, please 
let me know (because of the reinvented wheels ;-)

ciao,
Manuel
