Dependecies of signals not in always blocks

We can now see which signals affect which signals that are not assigned in always blocks using iverilogs nexus setup.
This currently only works for full signals and I have an error with LPMs currently. Todo next is fix error with LPM and
also get the bit slices of these signals
Fixed LPM problem by commenting out.

I'm still pretty mistified how a LPM can connect to another LPM without a wire or reg in between. Also, when I was
adding LPMs to LPMs, I was getting an endless loop. So that is commented out for now. I will go back and take a look at
the problem later. Now we just need to solve the slicing problem.
