+Some incomplete notes for javascript programmers:
+
+On page load, existing rows are initialized by passing values to addRow
+based on existing cgi values.  An empty row (marked with the 'emptyrow' 
+attribute) is created by invoking addRow without values.  After that, 
+to keep the non-empty row count (totalrows) accurate, use newEmptyRow to 
+create the next row.  There should only be one empty row at a time.
+
+Global vars:
+total_el  - element for displaying total number of rows
+totalrows - total number of non-empty rows
+rownum - really more of a "next row" value, used by addRow
+allrows - array of tr elements, one for each row
+
+Don't confuse the global rownum with the element attribute rownum
+that is set as a reference point on some of the elements generated
+by this script.  They have different values.
+
+Some of the functions:
+updateTotalRow() - updates total_el based on value of totalrows
+addDeleteButton(searchrow) - adds delete button to searchrow
+newEmptyRow() - replaces old empty row
+deleteRow() - removes the row specified by this.rownum
+addRow(values) - adds a new row (marked as empty if values aren't specified)
+
+This mason element is currently only used by misc/batch-cust_pay.html, 
+and probably should be cleaned up more before being used by anything else.
