 =item &get_sequence_assessment_data()  
   
 Use lonnavmaps to build a data structure describing the order and   
 assessment contents of each sequence in the current course.  
   
 The returned structure is a hash reference.   
   
 { title => 'title',  
   symb  => 'symb',  
   src   => '/s/o/u/r/c/e',  
   type  => (container|assessment),  
   num_assess   => 2,               # only for container  
   parts        => [11,13,15],      # only for assessment  
   response_ids => [12,14,16],      # only for assessment  
   contents     => [........]       # only for container  
 }  
   
 $hash->{'contents'} is a reference to an array of hashes of the same structure.  
   
 Also returned are array references to the sequences and assessments contained  
 in the course.
