+Creates table used to display and set course configuration items.
+
+Inputs: $cdom,$items,$ordered,$settings,$rowtotal,$crstype
+where $cdom is course's domain, $items is HASH ref for current config
+item, $ordered is ARRAY ref of items to include in row in 
+display order, $settings is HASH ref of current values forrow,
+$rowtotal is SCALAR ref used to accumulate row count, $crstype is

+Returns: $datatable
+HTML mark-up of data table which accumulates individual rows.  
+
+=item nothidepriv_row()
+
+Creates row containing form elements used to display and set

+Inputs: $item,$settings
+where $item is print_header_format, and $settings is a HASH ref
+of the current values stored for print_header_format.
+
+Returns: $output
+HTML mark-up containing Javascript functions: reOrder() and getIndexByName()
+used to dynamically update position selectboxes, and HTML table elements
+for the "Print header format" row.

+=item position_selector()
+
+Creates a select box which can be used to reorder substitutions
+and text included in a printout header. 
+
+Inputs: $pos,$num,$maxnum
+where $pos is current position, $num is the unique identifier,
+and $maxnum is the total number of items (both substitutions
+and text in the printout header.
+
+Returns: $output
+HTML mark-up for the selectbox and a hidden form element containing 
+the current position.   
+
+=item substitution_selector()
+
+Creates a combination of select box for choosing an item 
+(student name, course ID or assignment note) to substitute, 
+and a corresponding size limit in the header used for printouts.
+
+Inputs: $num,$subst,$limit,$crstype
+where $num is the unique identifier, $subst is the current 
+substitution (n,c or a, for name, course or note respectively,
+$limit is the current size limit (integer), and $crstype is
+course type - course or community.
+
+Returns: $output
+HTML mark-up for selectbox and textbox (separate table cells).
