wiki sidebar confusion

[stephens999]

when you look at the side bar, it looks like there are some headings and subheadings...
It would be natural to expect that clicking on a heading would take you to a page with more info on the subheadings. So you can either go direct to the subheading from the top menu, or go to a heading
and get more details to decide which subheading you want to follow.

Eg if I click "benchmark examples" I should be taken to a page that includes links to each subheading
(R example 1 and R example 2).

but that isn't what happens -

It is confusing because from the top menu it looks like there are two examples
(R example 1 and R example 2) but actually there are more... just only available if
you click the "benchmark examples".

I think the "First course on DSC" heading works as expected, and we shoudl change the others to follow suite.
