 * Purpose: this function returns the portion of the data array

 * @see tripal_stock_views_data() --in tripal_stock.views.inc
 *
 * @todo add better support for is_obsolete -through a field handler
 * @todo Add support for the following tables: stock_cvterm, stock_pub, stock_genotype
 * @todo Add join to node table within if <chado/drupal same db>; also addd if not around nid field
