[Greasemonkey] Greasemonkey class libraries?

[Vectorspace]

I don't know if its possible, but I know that @include is not the way to 
do it - the websites that @include are simply the websites that the 
script is allowed to run on - Even if two scripts run on the same page, 
they can't access each other.
