The collaborationhub ToC should not be chained only to the collaborationhub content model. It should be reusable elsewhere.

This is three-fold:

• Separate collaborationhub ToC out into its own class

Potential future work:

• Add parser function to include a ToC from a parent collaborationhub in any wikitext page, and mark the page as part of the collaborationhub We are not doing this anymore
• If any automatic inclusion is implemented for collaborationhub pages that mark their parent hub somehow, make sure this also works for pages using the parser function
