Feature request: Folder structure for the default template

[nkottary]

The default template generated by create looks like this right now:

It would be good to have more folders here, for example:

Where app.jl is inside src etc.

@nkottary Thanks! Curious as to what would be the benefit? Our experience is that the users are having a hard time finding the files they need to edit when they are placed inside different folders. A flat hierarchy of a couple of files is much easier to work with.

The idea was that as the project grows larger I would have many files. So it would be easier for me to organize files into src, assets etc.
