Collapsed Topics and Weeks do not have meaningful comment headers.

I received a message from Jago Brown (jago@active-studio.com):

thank you for the col topics format - teachers here like it & i'm now testing
it on a moodle 2 upgrade. It took me a while to confirm who developed this,
maybe you should comment scripts for php documentor?:

/**

So I need to add my own to my code for identification and the php documenter.
