UI: Intuitive way to establish relations

[i-interprete-on-the-fly]

Currently the establishing of links between Nodes is a bit tedious. Adding the relations by entering their UID in a bigger node hierarchy with lots of requirements can get a bit messy when one tries to develop a specification document from the web UI. This is nothing major but some ideas:

Idea 1: Establish an autocomplete function (using I am imagining being able to find specification elements using parts of the title or even the statement maybe) such that the user gets node suggestions matching the current input.

Idea 2: Similar to the possibility of creating a child requirement to a section, one could provide a button for each of the relations defined in the grammar which would allow to quickly build a tree structure

Idea 3: Make some kind of graph - link - editing possible in the traceability navigator
