Clear documentation of directory structure

[h-a-n-n-e-s]

Is your feature request or improvement related to a problem?

For beginners it's hard to understand the directory structure described in the docs. The single-page apps introduction introduces a directory structure, but there is no template for this type of app.

The only two existing templates (simple-blog, simple-mpa) do not follow the above directory structure (acutally their structure seems to be completely different). Does that mean the structure depends on the type of app? That would be strange.
