[j-nsp] boolean math for communities

[Avram Dorfman]

JUNOS policy only supports boolean operators, aka "policy expressions" 
as members of policy chains. The operate on policies, not on 
communities.

You can do some pretty interesting things with it, both in 
import/export statements, and in policy subroutines. Read the docs 
carefully though they don't behave exactly as you might guess.

Also, if you can get a hold of the Juniper book (Juniper Networks 
Routers: The Complete Reference), if you're interested, my chapter 
there on policy goes into significant (some might even say painful) 
detail on how expressions & subroutines work & how you can use them.
