[==] is a NOT object. That is, it's [== 0], as 0==0 gives 1, and as 1==0 
gives 0.

With GridFlow, there is also [shunt], which is like [spigot] but has two 
outlets (or any number of outlets). You can use that to make a [spigot] 
and negation in a single box. (it's nearly the same as what is called 
[demux] in other libraries).
