IDE Improvements

[Feliix42]

After discussing this with @cmnrd I wanted to share a few things I noticed after using the Eclipse product I built from scratch using maven (based on commit 88c2dc0). Those are mainly just things I found odd, but maybe it makes sense to fix some of these issues:

• There does not seem to be a dedicated "Lingua Franca" project type. Instead, when creating a new project I'm offered the choice between either a General Project or language-specific things like C/C++/Java/PyDev. Maybe having a Lingua Franca Project type with a project skeleton would be a good idea?
• Christian told me that having a src/ directory for your code within a project is strongly encouraged. Maybe this could be part of aforementioned project skeleton?
• The diagram feature of the IDE is in my opinion a great help for developing reactor programs. Sadly, the feature is well-hidden in the IDE behind Window > Show View > Other ... > KIELER Lightweight Diagrams > Diagram, making it almost impossible to find if you don't know it exists. Maybe it would make sense to automatically open the diagram view when opening a LF file or making the view more accessible by placing it in the "Show View" menu? I possess no knowledge about what's possible to do in an Eclipse product, so these are just suggestions.

Let me know what you think, these are just my two cents as a new user.

These are all great points. But I'm sure not quite sure how to configure these things...

I've noticed this tutorial that might hold some answers...

I just added a creation wizard for new LF files. Similarity, a creation wizard for LF projects could be created.

Furthermore, the LF perspective is now active by default, which has a diagram view already opened.

These are really great improvements! Yes, we should also have an LF project creation wizard...

It seems that the only thing holding us back from closing this issue at this point is a project creation wizard. @a-sr: would you be able to bootstrap this? I can create the icons and fine tune text etc...

[cmnrd]

I think we can close this now, right @lhstrh?

I plan to close this with #829 by collecting the example code from files in the example directory rather than having copies of LF code in the Java/Xtend code because the stuff in the example directory gets tested in CI.
