Nested Nets

[moiri]

When writing something like net A {}{ box A() on fa }

it seems that the scope is messed up and the ports of box A are also checked in net A

[moiri]

from the code: in order to add the 'this' instance to the instance table we need to get the declaration of the net before we put another scope on the stack

There seem to be further problems with nested nets in hierarchy.test
