 * @file: THIS IS A TEMPLATE AND SHOULD NOT BE INCLUDED IN THE MODULE CODE
 *
 *   - Every instance of XXX should be replaced with the name of your table
 *   - If this is a base table (you want a view where every row is a row from this table)
 *     then change $data['XXX']['table'] to $data['XXX']['table']['base'] 
 *     and $data['XXX']['table']['database'] to $data['XXX']['table']['base']['database']
 *   - Relationships between this table and others: YYY is the table you are trying to join to this
 *     one. You want to join a table to this one if this table contains a foreign key to the other
 *     table. If the join between this table and another is through a linking table
 *     (ie: library-XXX/YYY => library_feature-XY => feature-XXX/YYY) then make the join in both
 *     directions (ie: in the file XXX.views.inc and the file YYY.views.inc
 *   - Create a field definition for each field in this table using the example fields already
 *     listed. Match the type of the database field to the field definition listed below.
 *     (ie: for a text/varchar field from the database use plain_text_field below)
 * 
 *  NOTE: Creating the table definition file is not enough. You also need to call the 
 *        retrieve_XXX_views_data() function from ../tripal_stock.views.inc:tripal_stock_views_data()
 *        by adding the following line:
 *           $data = array_merge($data, retrieve_XXX_views_data());
 *        to the function and including the file directly above the function (blow the function 
 *        header by adding:
 *           require_once('views/XXX.views.inc');
 *
 *  REMOVE THIS COMMENT IN THE COPY!
