Changes the standard SectionIndex menu type, so menu items will be prefixed with a number, based on the headertype used on the contentelements.

If first header is of type 1 (or default), then 1 digit number will be prefixed.

If the header following a header type 1, then 2 digit number will be prefixed and so on.

So a page with header types like this:

type1

type2

type2

type3

type2

type1

type1

would generate a menu like this:

1 header

1.1 header

1.2 header

1.2.1 header

1.3 header

2 header

3 header
