Detach node data manipulation UI from the meta environment and generate them as views in the application itself

[dema]

Currently, the easiest way of feeding data into an application is by using the built-in UI for that, which resides in the meta-environment.

This creates a dependency between the run-time and meta-environment.

Ideally, all the node data manipulation UI should be made of custom views that are part of the application itself. Better yet, the meta-environment should generate those views automatically and allow easy customization of those.
