This file should contain all Drupal hooks for interacting with nodes.

  // the node is displayed. It is node type agnostic so we can add content to
  // any node type. So, we use this function to add the content from all of our
  // theme templates onto our new node type. We will also use this function to
  // add content to other node types.

        // chado_<base table> convention then this is the default. In this case

        // world that is used to reference the template. This ID is used for
        // constructing URLs for the content. The tripal_toc_title contains
        // the title that should appear in the table of contents for this
