gridlayout of Bars with Clef

[Orm Finnendahl]

Hi,

 for a preface I need a grid layout of single bars with barlines on
the left and right hand side, a clef for each bar and some music
within.

Below is a first attempt which should demonstrate the basic idea. My
problems with this example:

1. The systemStartDelimiter of the bars of the first row is drawn
   across all staves.

2. I can't find a straightforward way to add a full size clef on the
   bars in the second and third row.

It might be that a different approach altogether is better and I'm
open for any suggestions.

\layout {
