This module will go in the 'contrib' directory, and will be very similar to the TOC filter in the taxonomy_assoc module. It will allow TOC's to be placed anywhere within the node's body, rather than just in the standard spot. It will allow custom links to be added to the TOC (with a weight), and automatic links to be removed. Category_display will not automatically output a TOC if one has been manually defined using the TOC filter.
