Show hidden neighbors

[ugurdogrusoz]

Add a new operation (at the very end) to the context menu of nodes (Show Hidden Neighbors) to show its hidden neighbors. So if A has 3 neighbors N1, N2, and N3, and N2 is currently visible but N1 and N3 aren't, and we issue this operation on A, we get N1 and N3 shown (unhidden) along with their incident edges, followed by an incremental layout call (we might need to put neighbors near the node as we unhide them so that incremental layout works better)!

I added this operation to ChiSE as described above.

This is great! Here are things that we need fix/improve:

• Neighbours -> Neighbors (we consistently use US English)
• Need to add the functionality to the View menu (View > Hide/Show > "Show Hidden Neighbors", right before "Show All")
• If a transition is among nodes to be unhidden, we should find any other neighbor of that transition and unhide them as well to keep the transition intact!
• If you choose synaptic cleft in the default diagram and hide it, and go to any one of its neighbors (e.g. SNARE in synaptic button) and call this operation nothing happens.
  Let's talk about how to cleanly implement the last two issues.
  We should transfer this new feature to the viewer as well!

I made these fixes other than the second one because I have confusion there. In context menu we know which node is on target and we can "Show Hidden Neighbors" of it. However, in the menu we do not have such a target. May it be "Show Hidden Neighbors of Selected" instead of "Show Hidden Neighbors".

You re right, lets name as you suggested.
