This patch does not add finger joints to the vertical walls to attach the
retainer walls as the walls are likely to be to small to be able to make use
of them. In hte long run they should be added, though.
It is based on TypeTray generator. The sh parameter replace the sx parameter.
It is not a subclasse of TypeTray in order to have the top and bottom at
the right place.
