// this template does not follow the typical Tripal API. Normally
// variables are expanded using the tripal_core_expand_chado_vars API
// function call, but expanding the relationships table does not yeild
// a meaningful order to the data.  Therefore, relationships are preprocessed
// into an array named 'all_relationships', which is used in the template below.
