Collect NetTran devices into islands. NetTran devices must be collected into islands because they are all a bi-directional mass. This is how vvp will process them and the code generator will need a head start organizing them.

Collect analog branches into islands. Discipline islands all along were intended to carry collections of analog branches, as well as the current switch modeling support.
