Improve interactive exploration of the model

[antoniogarrote]

The main goal of the app should be to allow users to explore the model, no matter which syntax you are using in a simple way.

There are many modes of interaction with the model right now in the application:

• The text in the monaco editor
• The navigator on the left for the different levels: files, modules, domain
• The graph visualiser
• The query tab

We need to make these modes work together, e.g. scrolling the text to the text for the node selected in the visualiser or in the graph.

Any idea that would allow users to explore the model efficiently can be added as long as it makes the interface more consistent
